A 950 kg car accelerates from 0 to 33 m/s in 11 seconds. a) Calculate the acceleration of the car b) Calculate the force needed to produce this acceleration c) The car claims a top speed of 110 miles/hr. Explain why there must be a top speed for any car

a) a=v-u/t

= 33/1 = 3

b) F = ma

= 950x3 = 2850

c) Friction and air resistance increases with speed, till frictional = max forward force, then force/acceleration is zero
