Question

Mass of car is 1000kg. Engine produces force of 10000 N. Calculate velocity of the car 3
after 5 Sec when started from rest.

Answer 1

Answer:

force = mass × acceleration

[ acceleration = v - u / t ]___(equation )

put the equation in the place of acceleration.

i.e.,

f = m × ( v - u / t )

10000 N = 1000kg × ( v - 0m/s / 5s )

10000 N = 200 kg × v

v = 10000N/200kg

v = 50m/s

hence , the velocity of car after 5 sec will be 50m/s .
