A truck 'A' of mass 1700 kg traveling east at a speed of 24 m/s crashes into a smaller, 1100 kg parked wagon 'B'. The two vehicles remain joined together after the collision. What is the velocity of the wreck immediately after the collision? Neglect friction against the road. fAns: 14.6 m/s]

A block of mass m = 1.0 kg sliding along a rough horizontal surface is traveling...

A block of mass m = 1.0 kg sliding along a rough horizontal surface is traveling at a speed v0 = 10.0m/s when it strikes a massless spring head-on (see figure) and compresses the spring a maximum distance X =0.25m. If the spring has stiffness constant k = 100. N/m, determine the coefficient of kinetic friction between block and surface.

Constants A 3.20 kg box is moving to the right with speed 8.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=(6.00 N/s2 )t2 What distance does the box move from its position at t=0 before its speed is reduced to zero? Express your answer with the appropriate units. If the force continues to be applied, what is the velocity...
