A particle of mass \(0.5\) kg starts from rest and moves along a straight line under the action of a force that varies with distance \(x\) (in metres) as \(F(x)=4x^{2}\) N, where \(x\) is measured from the starting point. The particle travels a distance of \(2.0\) m. (a) Find the speed of the particle after it has traveled \(2.0\) m. (b) Determine the average power delivered by the force over this interval (in watts).

Answer Options

A. speed = 5.0 m/s; average power = 7.0 W
B. speed = 6.5 m/s; average power = 10.0 W
Correct Answer C. speed = 6.5 m/s; average power = 8.8 W
D. speed = 7.2 m/s; average power = 9.5 W
Correct Answer
C
Correct Option:
speed = 6.5 m/s; average power = 8.8 W
