Question

What is the mass of the cart with a constant net forces of 200N is exerted to
accelerate from rest to a velocity of 40m/s in 10s.
G-R-E-S-A METHOD

Answer 1

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.
