The block of mass M slides back along the horizontal surface with a coefficient of kinetic friction ?k and eventually comes to a rest. In terms of v4, how far does the block slide during this final leg of its journey, and how long does this take? Can you calculate the total trip time from bullet impact to now?
A cart carrying a vertical missile launcher moves horizontally at the constant velocity of 30.1 to the right. It launches a rocket vertically upward. The missile has an initial vertical velocity of 40.33 relative to the cart.
A bag of cement of weight 375 N hangs from three wires as suggested in Figure P5.18. Two of the wires make angles θ1 = 55.0° and θ2 = 25.0° with the horizontal. If the system is in equilibrium, find out the tensions in the wires.
