Question

calculate the force required to impart acar the velocity of 30m/s in 10 second than the mass of than the car is 1500kg

Answer 1

Initial velocity (u) = 0 m/s

Final velocity (v) = 30 m/s

Time taken (t) = 10 seconds

Let the acceleration of the car be a.

Using first equation of motion:

$v = u +at$

$a = \frac{v-u}{t}$

$a=\frac{30}{10}$

a = 3 m/s^2

Now,

Mass of the car = 1500 kg

Force required = Mass × acceleration

Force = 1500 × 3

Force = 4500 N

Hence, the force required to impart the car with 30 m/s velocity in 10 seconds is 4500 N.

Answer 2

Answer is 4500 N

First need to find acceleration using first equation of motion and then by applying F=m×a.
