A net force of 125 N accelerates a 25.0 kg mass. What is the resulting acceleration?
The acceleration of an object can be calculated by using Newton's second law:
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:
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
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.

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.
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
Solve Kepler's 3rd Law for M. Your answer will be in kg
mass of the sun = 1.98892 × 10^30 kilograms

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?
As we know that
here we know that
so we will have
if finally the snowmobile comes to rest
So here we can say that
so now we have

The stress force that causes a mass of rock to pull or twist in opposite directions is called shearing.
Hope this helps! :)
Planet a has three times the mass of planet b and the same radius. from this information, what can we conclude about the acceleration due to gravity at the surface of planet a compared to that at the surface of planet b?
Hence mass grows 3 times - g will grow 3 times as well
SIZE AND DISTANCE BETWEEN THEM
F = 49N
I Took The Test!
here, F = 25 N
s = 3 m
Substitute it into the expression,
W = 25 * 3
W = 75 Joule
So, your final answer is 75 J
Hope this helps!
Which is an example of transforming potential energy to kinetic energy?

Two wagons of equal mass are filled with an equal mass of bricks. Person A pushes one wagon with twice the force that Person B pushes the second wagon. How is the acceleration affected? A. Person A's wagon will accelerate at twice the rate of Person B"s wagon. B. Person A's wagon will accelerate at 1/2 the rate of Person B's wagon. C. Both wagons will accelerate at the same rate, since the mass is the same.
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.
