You push horizontally on a 140-N box that is initially resting on a horizontal table. The coefficient of static friction between the box and the table is 0.75, and the coefficient of kinetic friction is 0.40. Find the friction force on the box if the push is equal to (a) 84 N; (b) 109 N.

A small 0.40-kg box is launched from rest by a horizontal spring
as shown in the figure below. The block slides on a track down a
hill and comes to rest at a distance d from the base of
the hill. The coefficient of kinetic friction between the box and
the track is 0.32 along the entire track. The spring has a spring
constant of 37.0 N/m and is compressed 30.0 cm with the box
attached. The block remains on...

7. X You decide to try out your new rifle on a test range. The manufacturer says that a mo=4 g bullet is fired initially at a velocity of Voi=400 m/s. You decide to use this information to find the coefficient of friction between a block of wood and a concrete patio on which the block, m=0.8 kg, rests. The bullet, when fired, passes entirely through the block and emerges from the other side at 120 m/s. The block of...

A 109 g wooden block is initially at rest on a rough horizontal surface when a 13.0 g bullet is fired horizontally into (but does not go through) it. After the impact, the block–bullet combination slides 6.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.750, determine the speed of the bullet (in m/s) immediately before impact. Can you please explain how to get the answer/why?

can you please help with part C thanks!
A 0.0230 kg bullet moving horizontally at 450 m/s embeds itself into an initially stationary 0.500 kg block. (a) What is their velocity (in m/s) just after the collision? 19.79 (b) The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.30 kinetic coefficient of friction. Now what is its velocity (in m/s)? 18.56 (c) The bullet-embedded block now strikes and sticks to a stationary 2.00 kg block. How far...
