Mention four physical properties of physics

Acar is going 5m/s around a bend with a radius of 10m/s why is the accelerant?

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?
