Question

2. A particle of mass m moves on a straight line with
its velocity varying with the distance travelled. If the
relation between velocity and distance is v = kx (K
is constant), then find the work done by the forces
during a displacement x = 0 to x = d.
​

Answer 1

Answer:

mk²d²/2

Explanation:

v=kx

work done by the forces : kinetic energy at d — kinetic energy at 0

=1÷2×m(vf²)—1÷2×m(vi²)

vf-final velocity

vi-initial velocity

mk²d²÷2
