Dynamics

I am having a little trouble with this problem. Please help.

Dynamics - The smooth ramp is hyperbolic in shape as described by the equation

I need some help with these 2 problems attached. Thanks.

Two problems on dynamics.

Two problems on dynamics.

The 10-kg mass of the pendulum is released from rest

I am having trouble with these two problems. Please help. Thanks

A set of four problems on dynamics

For detailed description with figs. please refer the attachment. Prob. 1 : A box slides down a ramp with two straight segments and on leaving the ramp it slides on a rough horizontal surface and then impacting a spring. To determine kinetic energy, velocity at different points and the compression of the spring. Prob. 2 : A projectile is launched which lands on a hill. To determine max. height, horizontal range, time of flight etc. Prob. 3 : To determine velocity, acceleration at different points of a two pulley system (free end of the string being pulled by hand) Prob. 4 : To determine velocity, acceleration at different points of a two pulley system (a load hanging from the free... click for more
