a small bullet of mass m= 6 g staright up collides which a massive block of wood. At the time of impact of the speed of the bullet is V_i = 8 m/s. The block has a mass m= 5 kg and is initially vest on the table as shown in the picture. In the collision the bullet gets embeded in the block. After the collision the block and bullet system rises up to a maximum height H. The collision process is extremly fast and only last 0.0150s.

a) Calculate the final velocity of the block and bullet system imediately after the collision

b) The average force the bullet exerted on the block during the collision.

c) The average force the bullet exerted on the bullet during the collision

d) Maximum height that the block and bullet will rise after the collision

e) mechanical energy of the block and bullet lost during the collision.

A bullet with mass m(lowercase m) is fired into a block of wood with mass M(uppercase M), suspended like a pendulum, and makes a completely inelastic collision with it. After the impact of the bullet, the block swings up to a maximum height h. Given the values of h = 5.00 cm = 0.0500 m, m = 6.75 g = 0.00675 kg, and M = 2.50 kg, (a) What is the (initial) velocity v_x of the bullet in m/s? (b)...

A rifle bullet with mass 15.0 g strikes and embeds itself in a block of mass 1.500 kg that rests on a frictionless, horizontal surface and is attached to a coil spring. The spring was relaxed at the beginning. The spring constant is 550 N/m. The initial velocity of the bullet was 700 m/s. The impact compresses the spring by x (see figure below). 1) Find the magnitude of the block's velocity (with the bullet stuck inside) after the impact...

A small bullet of mass m=0.27g and speed v=13m/s embeds in a block of mass M=0.98kg suspended by a massless string of length L, after a collision as shown in the figure. If the bullet will appear on the other side of the block M with a speed v'=3.6m/s, instead of being embedded in it, find the maximum height the block M can reach. (Take g=9.81 m/s2). Express your answer using two decimal places.

A wood block of Mass M=3.00 kg and rests horizontally at the bottom of a ramp. A bullet of mass m=0.0420kg with an intial velocity v0 is fired at the wood block and embedded inside the block. The wood blocl and the embedded bullet together move up the ramp and reach a vertical heigh of yf= 2.40m relative to the bottom of the rmap(yo=0) before sliding downward. Ignore friction/air resistance. a) What is the total mechanical energy of the block+bullets...

A 75 g bullet is shot at a initial horizontal velocity of 150 m/s and makes a completely inelastic collision with a 4.0 kg block of wood connected to a hanging pendulum. What is the maximum height the pendulum, containing the combined mass of the bullet and block of wood, reaches?

A bullet of mass m = 2.40×10-2 kg is fired along an incline and embeds itself quickly into a block of wood of mass M = 1.35 kg. The block and bullet then slide up the incline, assumed frictionless, and rise to a height H = 1.35 m before stopping. Calculate the speed of the bullet just before it hits the wood.

A bullet of mass m = 8.00 g is fired into a block of mass M = 180 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d =  2.10 m from the bottom of the table. Determine the initial speed of the bullet. m/s

10. A bullet of mass M1= 0.4 Kg moving with initial velocity V1i= 800 m/s gets embedded into a block of wood of mass M2= 3.6 Kg that was initially at rest (V2i=0). The block is attached to a spring having spring constant K=400 N/m. After making the inelastic collision, the bullet-block combination slides on a horizontal frictioless surface and compresses the spring. Part A The amount of compression distance  delta X by which the spring gets compressed by the bullet-block...

A 0.0111-kg bullet is fired straight up at a falling wooden block that has a mass of 3.34 kg. The bullet has a speed of 759 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a...
