Answer: Explanation: The acceleration of an object can be calculated by using Newton's second law: where F is the net force applied on the object m is the mass of the object a is its acceleration In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration: ## Related Questions Posted in Physics Which of the following is not an example of kinetic energy? mechanical energy nuclear energy electrical energy thermal energy It is only mechanical energy that is kinetic energy while the other choices are not kinetic energy. Nuclear, electrical and thermal are other types of energy. Hope this answers the question. Have a nice day. Feel free to ask more questions. Posted in Physics How would the acceleration of a chain of three shopping carts compare with the acceleration of a single cart if the same force acted on both? A. 1/3 as much the single B. 1/2 as much the single C. 3 times as much the single D. 2 times as much the single So in order to know the correct answer, let us analyze the problem. Given that a = F/m where a is acceleration, F is force and m is mass, here is the solution. a = F/m a' = F/3m a'/a = 1/3 Based on this, the correct answer would be option A. 1/3 as much the single Hope this helps. Posted in Physics What mass (in mg) does 2.63 moles of nickel have? To convert the amount in moles to units of grams, we need the atomic mass of nickel which is 58.69 g/mol. We multiply the number of moles to the atomic mass which cancels moles leaving us with units of grams. 2.63 moles ( 58.69 g/mol ) = 154.35 g Nickel Hope this answers the question. Have a nice day.

In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star? Express your answer (a)in kilograms and (b)as a multiple of our sun's mass.

I'll tell you how to do it but you must crunch the numbers.

Use Kepler's 3rd Law

T^2 = k R^3

where k = 4(pi)^2/ GM
G =gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2
M = mass of this new planet
pi = 3.14159265
T =3.09 days = 266976 seconds
R = (579,000,000km)/9 = 64333333.3 km

a)
Solve Kepler's 3rd Law for M. Your answer will be in kg

b)
mass of the sun = 1.98892 × 10^30 kilograms
Form the ratio
M(planet)/M(sun)

A snowmobile has an initial velocity of 3.0 m/s Part 1: If it accelerates at the rate of 0.5 m/s/s for 7.0 sec, what is the final vel.? Part 2: If it accelerates at the rate of -0.60m/s/s, how long will it take to reach a complete stop?

Part a) Part b) Explanation:

Part a)

As we know that here we know that   so we will have  Part b)

if finally the snowmobile comes to rest

So here we can say that   so now we have   Posted in Physics

Nuclear reactions result in tremendous amounts of a. uranium. b. energy. c. fission. d. mass.

. How much work in joules is done by a person who uses a force of 25 N to move a desk 3.0 m?

We Know, W = F * s
here, F = 25 N
s = 3 m

Substitute it into the expression,
W = 25 * 3
W = 75 Joule

Hope this helps!

A 4.3 kg bowling ball is initially at rest. If a 15 N force acts on it for 0.85 s, what is the final velocity of the bowling ball?

According to Newton's 2nd law of motion, F = ma ==> a = F / m =15/4.3 = 3.48 m/s^2. Now using kinematic equation, v=u+at => v= 0 + 3.48x0.85 => V= 2.958 m/s

(F)(M)=A Force times Mass equals Acceleration. The answer is TRUE. If the mass increases the number on the left side of the equation increases, thus increasing the right side as well. Posted in Physics The acceleration due to gravity on Earth is 9.80 m/s2. An African elephant can have a mass up to 6,050 kg. What is its weight? The weight on earth is equal to m*g, where m is the mass and g is the gravitational force. 6050 (m) * 9.8 (g) = 59290 Newtons.

If two carts collide, what type of collision will conserve both momentum and kinetic energy? a. head on b. perfectly inelastic c. none d. perfectly elastic

The appropriate answer is d. perfectly elastic. When a perfectly elastic collision occurs both momentum and kinetic energy are preserved. Momentum is the mass of an object times its velocity while kinetic energy is the energy that a moving object has due to its motion. In an elastic collision kinetic energy would be converted to some other form of energy.
