Question 1 Report

A force acts on a body for 0.5s changing its momentum from 16.0kg ms-1 to 21.0kgms-1, calculate the magnitude of the force
Answer Details
The magnitude of the force F can be calculated using the formula: F = Δp/Δt where Δp is the change in momentum and Δt is the time taken for the change. In this case, Δp = final momentum - initial momentum = 21.0 kg ms^-1 - 16.0 kg ms^-1 = 5.0 kg ms^-1 Δt = 0.5 s Substituting these values into the formula: F = Δp/Δt = 5.0 kg ms^-1 / 0.5 s = 10.0 N Therefore, the magnitude of the force is 10.0 N. Answer: 10.0N
