Answer 1

The velocity of the cannonball is 150 m/s,  the right option is B. 150 m/s.

The question can be solved, using Newton's second law of motion.

Note: Momentum of the cannon = momentum of the cannonball.

Formula:

• MV = mv................. Equation 1

Where:

• M = mass of the cannon
• m = mass of the cannonball
• V = velocity of the cannon
• v = velocity of the cannonball

Make v the subject of the equation.

• v = MV/m................ Equation 2

From the question,

Given:

• M = 500 kg
• V = 3 m/s
• m = 10 kg.

Substitute these values into equation 2.

• v = (500×3)/10
• v = 150 m/s.

 

Hence, The velocity of the cannonball is 150 m/s,  the right option is B. 150 m/s.
