A bullet with mass m = 40 grams traveling at v = 400 m/s strikes a block of wood suspended from a ceiling with a massless cord. The collision last for 15 milliseconds, and after it is completed the bullet embeds itself into the block. Then, the combined system rises to a maximum height has its swings upward as shown. The mass of the wooden block is M=5.0kg and the length of the cord is L = 1.25 m. Calculate...
A bullet of mass 5 g is fired at 502 m/s horizontally into a block of wood (2kg) initially at rest suspended on a massless string. The bullet embeds itself in the block of wood and the combination swings up. To what maximum height does the combination swing? Answer in CENTIMETERS with 3 sig figs.
A bullet of mass 0.056 kg traveling horizontally at a speed of 100 m/s embeds itself in a block of mass 1.5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? v= m/s (b) Calculate the kinetic energy of the bullet plus the block before the collision: K; = (c) Calculate the kinetic energy of the bullet plus the block after the...
A 15 g bullet strikes and embeds in a 2.2 kg block suspended at the end of a 1.1 m string. After the collision the string rises to a maximum angle of 25 degrees to the vertical. Find: a) the speed of the bullet: m/s b) the percentage loss in kinetic energy due to the collision: %
A 2 x 10^-3 kg bullet (m) is shot into a 5 kg block (M) of wood which is fixed to a friction less horizontal surface. The bullet hits the block at v = 500m/s 1) Calculate the magnitude of the momentum of the bullet as it hits the block. 2) The bullet embeds itself in the block. How much work is done by the resistive force due to the block in bringing the bullet to rest? 3) The average...
A bullet of mass 0.017 kg traveling horizontally at a high speed of 210 m/s embeds itself in a block of mass 4 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? Vf = m/s ) Calculate the total translational kinetic energy before and after the collision. Ktrans,i = Ktrans,f = (c) Compare the two results and explain why there is a...
A bullet of mass 0.017 kg traveling horizontally at a high speed of 210 m/s embeds itself in a block of mass 5 kg that is sitting at rest on a nearly frictionless surface.

A bullet of mass m = 23 g is fired into a wooden block of mass M = 4.4 kg as shown in the figure below. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing the block to then swing as shown in the figure. If the block reaches a maximum height of h = 0.25 m, what was the initial speed of the bullet? m/s Bullet
Forensics Test 1 2 3 4 As part of a forensics test, a 0.005 kg bullet is fired into a 0.52 kg stationary wooden block. The bullet becomes embedded in the block. The initial speed of the bullet is 390 m/s. 1) What is the initial velocity of the center of mass of the bullet-block system before the collision? m/sec Submit 2) What is the velocity of the block (with the embedded bullet) after the collision? m/sec Submit Help 3)...
A 35 g bullet is fired horizontally into a hanging wooden block (mass 1.7kg) as shown in (Figure 1). The bullet's initial speed is 300 m/s . The bullet becomes embedded in the block, which then swings upward some height. What is the maximum height to which the block rises? Instead of getting embedded in the block, the bullet passes completely through it, emerging on the other side with a speed of 100 m/s . How high does the block...
