To Choose: The correct option.
Answer to Problem 9STP
Option D.
Explanation of Solution
Given:
The velocity-time graph depicting the motion of the cart.
Formula used:
The acceleration of an object can be obtained by,
Where,
From Newton’s Second law of motion:
Where, a is the acceleration, m is the mass and
Calculation:
Considering the graph, the acceleration of the car can be calculated as follows:
Take time interval between
Then, the force exerted on a 16kg cart will be:
Conclusion:
Thus, the force acting on the given cart is 32N.
