A bullet of mass < 7.5 + A > g is fired into a block of wood of mass < 0.35 + B/100 > kg suspended by a < 0.80 + C/10 > m long string. If the block swings up so the strings make an angle of 64.0 from vertical, what was the initial speed of the bullet?
A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...
A bullet with some mass, m, and initial speed, vi, collides with a wooden block of mass M that is hanging at the end of a light rope. The bullet imbeds itself in the block and the block and bullet swings upwards reaching a maximum height of h above the initial point of the collision. a. A scientist can measure the masses and the height, show that the initial speed can then be calculated from the following equation: vi= (m+M)/m×root...
A bullet of mass < 7.5 + A> g is fired into a block of wood of mass < 0.35 + B/100> kg suspended by a < 0.80 + C/10> m long string. If the block swings up so the strings make an angle of 64.0° from vertical, what was the initial speed of the bullet? A=2 B=8 C=0
A bullet of mass m is shot at speed v toward a pendulum bob of mass M. The bullet penetrates through the block and emerges on the other side traveling at speed v/2. 1. What is the speed Vblock of the block immediately after the bullet emerges from the block? Give your answer in terms of m, v, and M Vblock = 2: To what maximum height h does the block rise? Give your answer in terms of m, v,...
A bullet of mass 5 g hits a block of mass 10 kg. In one situation, the bullet embeds in the block. In another situation, the bullet bounces backwards in an elastic collision. What is the relationship between the speeds of the block in the two situations. A Block is twice as fast if the bullet embeds in the block B Block is twice as fast if the bullet bounces C Block is a factor of square root of two...
A block of mass M is suspended by a massless wire of length L and, after a completely inelastic collision with a bullet of mass m, swings up to a maximum height y < L. Find: (a) the speed v of the block with the bullet in it immediately after impact; (b) the tension force T in the wire immediately after impact; (c) the initial horizontal velocity vo of the bullet. Explain pendulum tension please.
A bullet of mass 0.7 kg hits a block and gets stuck with it with a velocity of 30m/s. The block has a mass of 50 and it is hanging by a string of length 15m. 1. find the T of the oscillations 2. Max acceleration of object after the collision in this periodic motion. 3. How long does it take the object to come back to rest?
Please help me with this. thank you Prob3: In a system of ballistic pendulum, a bullet of mass 5.0 g makes a completely inelastic collision with a block of mass of wood of mass 2.0 kg which is suspended like a pendulum. After the impact, the block swings up to maximum height of 3.0 m. What is the initial speed of the bullet?
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: %
