Question

what would be the force required to stop a car of mass 1000kg in 2 second if it is moving with velocity of 5 meter per second​

Answer 1

Answer:

2500N

Explanation:

Answer 2

Answer :

Mass of car = 1000kg

Initial velocity = 5m/s

Final velocity = zero

We have to find force required to stop the car.

★ As per newton's second law of motion, force is defined as the rate of change of linear momentum.

• Force is a polar vector quantity having both magnitude as well as direction$.$

Mathematically, F = dp/dt

F denotes force

dp denotes change in momentum

dt denotes change in time

→ F = m(v - u)/t

• v = final velocity
• u = initial velocity

→ F = 1000(0 - 5)/2

→ F = 500(-5)

→ F = -2500N

Negative sign shows regarding force.
