Question

A resultant force of 4.0 N acts on an object of mass 0.5 kg for 3.0 s. What is the change in velocity caused by this force? (A) 4.0 m/s (B) 6.0 m/s (C) 12 m/s (D) 24 m/s

Answer 1

The change in velocity, Δv, caused by a force F acting on an object for a time t can be calculated using the equation: Δv = F * t / m, where m is the mass of the object.

For this problem, the change in velocity can be calculated as follows:

Δv = 4.0 N * 3.0 s / 0.5 kg = 24 m/s.

Therefore, the answer is (D) 24 m/s.
