Chapter 3, Problem 50TS

Alex, who has a mass of 100 k g , is skateboarding at 9.0 m / s when he smacks into a brick wall and comes to a dead stop in 0.2 s .

(a) Show that his deceleration is 45 m / s 2 .

(b) Show that the force of impact is 4500 N . (Ouch!)

How much does a 0.25kg apple have with an acceleration of 9.8m/s
Consider a mass of 1kg accelerated 1m/s2by a force of 1N. Show that the acceleration would be the same for a force of 2N acting on 2Kg.
Forces of 3.0 N and 4.0 N act at right angles on a block of mass 2.0 kg. Show that the acceleration of the block is 2.5 m/s 2.
