Dynamics

A constant force of F acts on a mass as
shown. The mass starts its motion from rest at
position 1, the unstretched length of the spring
is 250 mm, and the spring modulus is k =
1,5 kN/m. Neglecting the friction, determine
the required force ? to cause the 2 − kg mass
to have a speed of v2 = 1,5 m/s at position 2.
