te M of estion M A mass M = 1.2 kg is released from rest. From the initial height of 90 cm above the ground, the mass drops from an free spring (neither compressed, nor extended) of constant k = 580 N/m. The maximum compression of the spring, due to the impact of the dropping mass is dh = 180 mm. Analyse the system with respect to the balance of energy, and the apply the conservation of energy, considering the...

PLEASE ANSWER STEP BY STEP A thrill-seeking cat with mass 4.00 kg is attached by a harness to an ideal spring of negligible mass and oscillates vertically in SHM. The amplitude is 0.050 m, and at the highest point of the motion the spring has its natural unstretched length. Calculate the elastic potential energy of the spring (take it to be zero for the unstretched spring), the kinetic energy of the cat, the gravitational potential energy of the system relative...

A mass 3 kg is released from rest at a height of 5 meters and slides down a frictionless curve. There is a patch that is 3 meters long with a kinetic coefficient of 0.2. Beyond that friction patch is a spring with a spring constant of 400 N/m. (There is no friction under the spring.) Calculate the maximum compression distance (x) needed to stop the mass the first time It compresses the spring. Calculate where exactly the mass stops...

3m Susand a) A block with a mass of 10.0 kg is AS released from rest at the top of an 1 00.kg inclined track (0 = 30°), at point A, 3.0m above the horizontal (see the figure). The track A to B has a coefficient of kinetic friction of 0.10. The horizontal portion of the track, B to C, is 4.Om long - 4m and is frictionless. At point C, where the horizontal track ends, the block touches the...
