If a car travels around a gentle curve on a highway at 60 km/h, does the velocity change

A youngster having a mass of 50.0 kg steps off a 1.00 m high platform. If she keeps her legs fairly rigid and comes to rest in 10.0 ms, what is her momentum just as she hits the floor? What average force acts on her during the deceleration?

The acceleration due to gravity on the moon is about 5.4 ft/s2. If your weight is 150 lbf on the earth: What is your mass on the moon, in slugs.

You observe a hockey puck of mass 0.12 kg, traveling across the ice at speed 18.3 m/sec. The interaction of the puck and the ice results in a frictional force on the puck, f = 0.14 N. Calculate: the stopping distance for this puck.

A 5.00-kg block of ice is sliding across a frozen pond at 2.00 m/s. A 7.60-N force is applied in the direction of motion. After the ice block slides 15.0 m, the force is removed. The work done by the applied force isA 5.
