Answer:
Force applied on the cart = 200 N.
Initial velocity = 0 m/s.
Final velocity = 40 m/s.
Time taken = 10 s.
Mass of the cart = ?
Acceleration = v-u/t
So, a = 40-0/10
⇒ a = 40/10
⇒ a = 4 m/s²
Now, Force = mass × acceleration
⇒ F = ma
⇒ m = F/a
⇒ m = 200/4
⇒ m = 50 kg
Hence, the mass of the cart = 50 kg.
So here,
Force is said to be ye product of mass and acceleration.
Acceleration is the rate of change of velocity.
Velocity is the displacement of the body per unit time.
