A physics student rolls at 2.00 m/s in a frictionless chair (total mass 97.0 kg) toward another physics student in a frictionless chair (total mass 103 kg) who is initially at rest. They collide and push each other away, and the first student+chair rolls off at a speed of 2.30 m/s opposite the initial direction. a) What is the velocity of the second studentchair combination?

How much fuel would be needed for a 1000-kg rocket (this is its mass with no fuel) to take off from Earth and reach 1000 m/s in 30 s? The exhaust speed is 1000 m/s.
The driver of a three-wheeler moving with a speed of 36 km/h sees a child standing in the middle of the ro ad and brings his vehicle to rest in 4.0 s just in time to save the child. What is the average retarding force on the vehicle? The mass of the three-wheeler is 400 kg and the mass of the driver is 65 kg.
Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 6.50 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.245 m from the one remaining 2.00 kg bowling pin. Treat both the ball and the pin as point objects, and determine the magnitude of the force of gravity ?⃗ grav between them.
Spectators watch a bicycle stunt rider travel off the end of a60.0° ramp, rise to the top of his trajectory and, at that instant,suddenly push his bike away from him so that he falls verticallystraight down, reaching the ground 0.550 s later. Howfar from the rider does the bicycle land if the rider has massM = 72.0 kg and the bike has mass m = 12.0 kg? Neglect airresistance and assume the ground is level.
A small block of mass m, = 0.855 kg is released from rest at the top of a curved wedge of mass m, = 8.80 kg, which sits on a frictionless horizontal surface as in figure (a).

You are standing on a large sheet of frictionless ice and holding a large rock. In order to get off the ice, you throw the rock so it has velocity 12.0 m/s relative to the earth at an angle of 35.0∘ above the horizontal. Your mass is 77.0 kg and the rock’s mass is 3.00 kg. a) What is your speed after you throw the rock?
