Question

The speed of a 500 g cricket ball changes from 10m/s to 30m/s in just 7 seconds. What is the force acting on the cart?

Answer 1

The force acting on the cart is 1.43 N.

What is force?

Force can be defined as the product of mass and acceleration.

To calculate the force acting on the cart, we use the formula below.

Formula:

• F = m(v-u)/t................. Equation 1

Where:

• F = Force acting on the cart
• m = mass of the cart
• v = Final velocity
• u = initial velocity
• t = time

From the question,

Given:

• m = 500 g = 0.5 kg
• v = 30 m/s
• u = 10 m/s
• t = 7 seconds

Substitute these values into equation 1

• F = 0.5(30-10)/7
• F = 10/7
• F = 1.43 N.

Hence, the force acting on the cart is 1.43 N.
