Question
(a)
Explain the meaning of spring force and the graph of spring force against position
(b)
The 8735 kg helicopter is takes off vertically with its rotor exerting a constant
upwardthrust of 117 kN. Determine how far it has risen if its velocity is 11 m/s.
In Figure 4 (c), the 30 N block is moving up the smooth inclined surface at velocity
and constant force of 2 m/s and 15 N, respectively.
(i). Draw the kinetic diagram of all forces exerted on box
(ii). Calculate the velocity of the block when it has moved 1 m up the surface from
its present position.
(c)
