A mass of 40tonnes is accelerated from rest for 20s then runs uniformly for 5 mins and is finally brought to rest. Assuming acceleration and deceleration are 0.7m/s2

calculate;

a) total distance travelled)

b)total force required during this period (ignoring friction)

for a I have calculated 4480m

for b I have calculated 28kn. (F=m x a = 40000 x0.7)
