A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...

M 7 A mass M = 1.2 kg is released from rest. From the initial height of 75 cm above the ground, the mass drops from an free spring (neither compressed, nor extended) of constant k = 590 N/m The maximum compression of the spring, due to the impact of the dropping mass is sh = 160 mm. Analyse the system with respect to the balance of energy, and the apply the conservation of energy, considering the ground level as...

A 1-kg pellet travels with velocity 160 m/s to the right when it collides with a 39-kg hanging mass which is initially at rest. After the collision, the pellet remains lodged in the hanging mass, i.e., it is a completely inelastic collision. The hanging mass (+pellet) then swings upward and reaches a maximum height hmax before swinging downward again. Assume that no external forces are present and therefore the momentum of the system is conserved. What is the velocity vf...

A track consists of a frictionless incline plane, which is a height of 0.5 m, and a rough horizontal section with a coefficient of kinetic friction 0.02. Block A, whose mass is1.5 kg, is released from the top of the incline plane, slides down and collides instantaneously and inelastically with iden tical block B at the lowest point. The two blocks move to the right through the rough section of the track until they stop. Determine the initial potential energy...
