An 865 kg (1912 lb) dragster, starting from rest, attains a speed of 26.7 m/s (59.8 mph) in 0.59 s.
(a) Find the average acceleration of the dragster during this time interval.
m/s2
(b) What is the magnitude of the average net force on the dragster during this time?
N
(c) Assume that the driver has a mass of 68 kg. What horizontal force does the seat exert on the driver?
N

acceleration= changevelocty/time
Forceaverage= mass*acceleraltion
Forceseat= driver mass*acceleration 
A 69 kg diver jumps off a 10.4 m tower.
(a) Find the diver's velocity when he hits the water.
m/s
(b) The diver comes to a stop 2.0 m below the surface. Find the net force exerted by the water.
N 
Lee Kite just a fellow question.
Why do you need all this help on Physics?
You need to do your work on your own.
