You are capable of pushing a 5.2 kg box hard enough to create an acceleration of 0.38 m/s2. When you push a second box with the same force, it only accelerates at 0.21 m/s2. What is the mass of the second box?
Homework Answers
Force needed the push the first box is given by
F=ma =5.2*0.38 =1.976 N
Since same force is used to push the second box ,the mass of the second box is
m2=F/a2 = 1.976/0.21
m2 = 9.41 kg

Question 14 4 points Save Answer You are pushing a 3.15-kg box toward the right as it moves, in the direction of your push, over a patch of rough grass. If the magnitude of your push is 18 4 N, and the coefficient of kinetic friction with the grass is 0.350, what will be the magnitude and direction of the acceleration of the box? O a.-2.4 mis2 b. -1.2 m/s2 O c. 1.2 m/s2 d.2.4 m/s2

A pushing force is applied to a 3.5-kg box. It starts from 2m/s and accelerates to 5.2 m/s covering the distance of 6 m. (a) Find the work done by the pushing force. (b) If friction is negligible, find the average force exerted on the box. Find (c) an impulse of the force, (d) the change in the momentum, (e) the final kinetic energy.

A 22.8 kg box is placed at the bottom of a 39.7° ramp whose surface is rough enough that the coefficient of kinetic friction is 0.222. You push on the box parallel to the ramp's surface, so that the box accelerates up the ramp at 0.911 m/s2. What must be the force (in N) supplied by you?

A box of mass M = 0.2kg starts out at rest on a horizontal table. The surface is not frictionless. At t = 0.75s you start pushing on the box horizontally in the +x direction, causing it to speed up. The force you push with is not necessarily constant. You stop pushing on the box at t-2s, after which it slides on its own as it slows down and comes to rest at t = 4s. Between t-2s and t...
