Question

Calculate the force rto impart a car,a velocity of 30m/s in 10 sec . The mass of the car is 1500 kg

Answer 1

Answer:

4500 newton is the force that is imparted a car.

Explanation:

Mass of car (m)=1500 kg

Velocity of car (v)=30m/s

Time = 10 seconds

Force = m × a

Force = m × ∆v/∆t

Force = 1500 × 30/10

Force = 1500 × 3

Force = 4500 newton

Note

Here, a is the acceleration of car

∆v/∆t is the rate of change of

velocity per unit time.

acceleration is rate of change of velocity per unit time.

i.e.,

a=∆v/∆t
