Using law of conservation of momentum,
m1u1 + m2u2 = m1v1 + m2v2
30 x 500 = 500 x 6 + 30 v2
V2 = 400 m/s
Again using law of conservation of momentum,
500 v1 + 0 = 30 x 400 + 0
Velocity, v1 = 24 m/s

21. Two 500 g blocks of wood are 2.0 m apart on a frictionless table. A 10 g bullet is fired at 400 m/s blocks. It passes all the way through the first block, then embeds itself in the second block. The speed of the first block immediately afterward is 6.0 m/s. What is the speed of the second block after the bullet stops in it?
A bullet with a mass of 1.60 g is fired horizontally at two blocks resting on a smooth and frictionless table top as shown in the Figure. The bullet passes trhough the first 1.60 kg block, and embeds itself in a second 1.80 kg block. Speeds v1 = 1.60 m/s and v2 = 4.60 m/s, are thereby imparted on the blocks. The mass removed from the first block by the bullet can be neglected. Find the speed of the bullet...
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.20 kg) and embeds itself in block 2 (mass 1.85 kg). The blocks end up with speeds v1 = 0.510 m/s and v2 = 1.38 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1....
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.04 kg) and embeds itself in block 2 (mass 1.69 kg). The blocks end up with speeds v1 = 0.550 m/s and v2 = 1.40 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1....
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.36 kg) and embeds itself in block 2 (mass 1.87 kg). The blocks end up with speeds v1 = 0.500 m/s and v2 = 1.35 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1.
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.33 kg) and embeds itself in block 2 (mass 1.89 kg). The blocks end up with speeds V1 = 0.560 m/s and v2 = 1.42 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1....
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.13 kg) and embeds itself in block 2 (mass 1.65 kg). The blocks end up with speeds V1 = 0.550 m/s and v2 = 1.45 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1....
In Figure (1), a 3.50 g bullet is fired horizontally at two blocks at rest on a frictionless table. The bullet passes through block 1 (mass 1.37 kg) and embeds itself in block 2 (mass 2.01 kg). The blocks end up with speeds v_1 = 0.600 m/s and v_2 = 1.45 m/s (see Figure (2)). Neglecting the material removed from block 1 by the bullet, find the speed of the bullet as it (a) leaves and (b) enters block 1....
A 2.9 kg block of wood sits on a frictionless table. A 3.0 g bullet, fired horizontally at a speed of 480 m/s goes completely through the block emerging at a speed of 250 m/s. What is the speed of the block of wood immediately after the bullet exits?
refer to picture. refer to pic Two blocks of masses 0.990 kg and 2.00 kg are at rest on a frictionless surface. A 10.0 g bullet is fired horizontally at a speed of 750 m/s and embeds itself inside the smaller block, as shown. The block with the bullet then collides elastically with the larger block. Determine, the speed of the smaller block after the bullet embeds itself inside. a. the amount of thermal energy produced. b. the final speed...
