A particle of mass \(0.5\) kg moves along a straight line under the action of a variable force \(F(x)=4x^{2}\) N, where \(x\) is the displacement in metres measured from the starting point. The particle starts from rest at \(x=0\). (i) Find its speed when it reaches \(x=2\) m. (ii) The particle then moves an additional 1 m while a constant opposing force of \(5\) N acts on it. Find its speed at \(x=3\) m.

A. 6.00 m\/s, 9.50 m\/s

B. 5.23 m\/s, 10.87 m\/s

C. 7.01 m\/s, 12.45 m\/s

Correct Answer D. 6.54 m/s, 11.14 m/s

Correct Answer

Correct Option:

6.54 m/s, 11.14 m/s
