(ii) A bullet of mass m is fired vertically from below and into a thin block of wood of mass M that is initially at rest, supported by a thin sheet of paper. The bullet blasts through the block, and the block rises to a height of H above its initial position before falling. The bullet continues after passing through the block and rises a height of h before falling. In the questions below, the answers should be expressed only in terms of the parameters of m, M, h, H and g. Find expressions for the upward velocities of the bullet vm and the block VM immediately after the bullet exits the block. (a) Use conservation of momentum to express the speed of the bullet v, before it enters the block of wood. (b) Obtain expressions for the mechanical energies of the system E, before and Er after the inelastic collision between the bullet and the block. (c) (d) Express the energy dissipated in the block.

Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
If the motion can only be defined by the movement of the center of mass and the rotation of the object can be neglected, what is this object??
A bullet, having a mass of 0.0400 kg moving with a velocity of 450 m/spenetrates a distance of 0.0800 m into a wooden block firmly attached to theearth. Assuming a constant accelerating force, compute the following: a) the acceleration of the bullet,b) the accelerating force,c) the time of acceleration, andd) the impulse of the collision.
A car is initially traveling at a speed of 90 km/h, suddenly brakes so that the speed becomes 36 km / h in an interval of 6 s. If style that stops the car at 3200 N, what is the mass of the car?
Most of us know intuitively that in a head-on colli-sion between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Whyis this? Many people imagine that the collision forceexerted on the car is much greater than that exerted onthe truck. To substantiate this view, they point out that thecar is crushed, whereas the truck is only dented. This ideaof unequal forces, of course, is false; Newton’s third lawtells us that both objects are acted upon by forces of thesame magnitude. The truck suffers less damage because it is made of stronger metal. But what about the two driv-ers? Do they experience the same forces? To answer this question, suppose that each vehicle is initially moving at 8.00 m/s and that they undergo a perfectly inelastic head-on collision. Each driver has mass 80.0 kg. Including the masses of the drivers, the total masses of the vehicles are 800 kg for the car and 4 000 kg for the truck. If the colli-sion time is 0.120 s, what…
