- A 59.5 kg man standing on a frictionless surface pushes two large boxes in opposite directions as shown. Initially everything is a rest. If the left box has mass 41.5 kg and final speed 3.25 m/s, and the right box has mass 27.0 kg and final speed 2.00 m/s, what is the final velocity (magnitude and direction) of the man? Let the positive direction be to the right.Albert and his friend Isaac are standing in the middle of a sheet of ice in the student parking lot when they decide to give each other a push. If Albert has a mass of 73.6 kg and moves to the right at 1.30 m/s after the push, how fast will Isaac move if his mass is 51.8 kg? m/sA Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice.

- d and eDan is gliding on his skateboard at 2.56 m/sm/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6.22 m/sm/s (as measured by an observer on the ground). Dan's mass is 42.1 kgkg and the skateboard's mass is 5.99 kgkg . If the jump requires 0.122 ss to complete, what average force did Dan exert on the skateboard?Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 3.2 × 104 kg (about 32 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of km/s. As you pass the location km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of N for 23.0 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?) 7₁ = m
