Blocks A and B, with masses Ma= 5kg and Mb= 3kg, respectively, are connected by a spring of stiffness k= 20 N/m and unstretched length of 0.75m. The blocks are at rest and seperated by the distance 0.75m when block B is given a velocity to the rightwith magnitude v0=15m/s. The friction between blocks and the horizontal surface on which they rest is negligible. The picture given looks like: [A]---------[B] where the dashed line is the spring. Determing the maxium...

Two blocks of masses m_1 = 4 kg and m_2 = 5kg are connected by a massless string that passes over a massless frictionless pulley as shown in Fig. 6.34. Block m_1 is initially at rest on a smooth horizontal plane while block m_2 is at a height h = 0.75 m above the ground. Use conservation of mechanical energy to find the speed of the masses just before m_2 hits the ground.

Initially a 4kg mass and a 2kg mass are at rest on a friction free surface held together by a string. Between these two masses is a spring compressed by 0.1 m. At t= 0 , the string is cut and the two masses allowed to fly apart. When the masses are far apart, the velocity of the 2kg mass is 2m/s. 1) What is the velocity of the 4kg mass?? 2) Is momentum conserved in this process, i.e is...

1.) AT the top of a 30 m hill is a 5kg mass. It is loaded into a spring cannon. The cannon's spring has a constant k=400 N/m and the spring is compressed 40cm. The mass is initially at rest. Therefore there is no friction. (A.) What was the stored energy in the spring before it was released? (B.) What was the gravitational potential energy of the mass with respect to the bottom of the hill? (C.) What was the...
