Question

find the value of that force which produces velocity of 30m/s of a motor car in 12 second mass of motor car is 1,000kg.​

Answer 1

Answer:

1250N

Explanation:

Assuming that the car is at rest initially; using equations of motion we get

a = (v-u)/t

a = (30 - 0)/12 = 15/6 m/s^2

Now Force = (mass)(acceleration) = (1000)(15)/12 = 1250 N
