Please see question below. I would like it completed in word format rather than hand written please.

4(a)

A vehicle of mass 1200 kg accelerates uniformly from rest to a velocity of

15 m/s in 5 seconds. It continues at this velocity for 15 seconds before decelerating uniformly at a rate of 5m/s2 to rest. Determine the following:(i)The acceleration

(ii)The time taken to decelerate from 15 m/s to rest

(iii)The total distance travelled                                                                  

4(b)

A racing car of mass 850 kg accelerates from 20 km/h to 160 km/h over a distance of 300 metres. Frictional forces and wind resistance can be assumed to be 800N. Determine the following:

(i)The average acceleration

(ii)The time taken to accelerate from 20 km/h to 160 km/h

(iii)The tractive force produced by the car to provide this acceleration

(iv)The car finally reaches a speed of 250km/h. Friction and wind resistance are 1800 N at this speed. What power output is required to maintain this speed?         

4(c)

A space vehicle travelling at a velocity of 6000km/h separates into two parts of mass 1200 kg and 300 kg. The two parts continue moving in the same direction with the lighter section moving at 6200km/h. Making use of the principle of conservation of momentum, determine the velocity of the heavier section after separation
