A Small pickup truck that has a caliper shell slowly coasts toward a red light with negligible friction. Two dogs in the back of the truck are moving and making various inelastic collisions with each other and the walls. What is the effect of the dogs on the motion of the center of mass of the system (truck plus entire load)? What is their effect on the motion of the truck?
Each Voyager spacecraft was accelerated toward escape speed from the Sun by the gravitational force exerted by Jupiter on the spacecraft.

A 6.00 kg box sits halfway up a 13.0 m long ramp that is inclined at an angle of 15.0o. You shove a second box, of mass 3.00 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.250. Where, from the bottom of the ramp, do they come to rest?
pls help asap!!!!!
As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. 100 my The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m₁ = 17.0 kg and m₂ = 44.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after the collision. p (kg. m/s) 40 V₂i Determine the velocity (in m/s) of car #2 before the collision. m/s t (s)
