Question

the mass of a car is 1500 kg the force required to impart to a car a velocity of 30 m s in 10 second starting from rest is what​

Answer 1

Answer:

The force required is 4500 N.

Explanation:

Mass of the car, m = 1500 Kg

Initial velocity of the car, u = 0 m/s

Final velocity of the car, v = 30 m/s

Time taken to make this velocity change, t = 10 s

Acceleration of the car can be found using the equation,

a = (v - u) / t

a = (30 - 0) / 10

a = 3 m/s²

The force acting on the car to make this velocity change is:

Force = mass × acceleration

          = 1500 × 3

Force = 4500 N

Answer 2

Given :

Mass (m) = 1500kg

Initial Velocity (u) = 0m/s

Final Velocity (v) = 30m/s

Time (t) = 10sec

To Find :

Force (F)

Solution :

Finding Acceleration

a = (v - u)/t

= 30/10

= 3m/s

Finding Force required.

as we know that,

Force = Mass * Acceleration

= 1500 * 3

= 4500N
