Question

A 1027 kilogram truck is resting at a stop light . The truck moves with a force of 1528 N for 22s.Then the trucktravels at a costent velocity for 10 seconds .Finally the truck stops with a force of 4056 N . Calculate the distance travelled by truck during this journey.?​

Answer 1

Answer:

Initial velocity of the truck, u=0

Distance covered by the truck, s=400 m

Time taken to cover that distance, t=20 s

Let the acceleration of the truck be a

s=ut+

a=2 m/s

Mass of the truck M=7 tonnes=7000 kg (∵1 tonne=1000 kg)

F=Ma=7000×2 =14000 N
