Question

A single force F of constant magnitude begins to act on a stone that is moving along an x-axis. The stone
continues to move along that axis. Which of the following can represent the stone's position?
x = 5t - 3
x = 5t2 + 8t - 3
x = -5t2 + 5t - 3
x = 5+3 + 4+2 - 3​

Answer 1

Explanation:

as the force is constant but not zero d^2x/dt^2 should be constant and not zero and positive giving answer as option b
