Leroy, who has a mass of 110 , is skateboarding at 9.4 when he smacks into a brick wall and comes to a dead stop in 0.2. Find his deceleration.Find the force of impact. (ouch!)

Force = Massx acceleration. Find the accel using v=u+at, solving for a.

v is the final velocity (0); u is the initial (9.4), t is time (0.2)

Then x by 110 kg. to get the force in Newtons.
