Question 5
A 0.021 kg bullet is shot horizontally and collides with a 2.35 kg block of wood. The bullet embeds in the block, and the block slides along a horizontal surface for 1 m. If the coefficient of kinetic friction between the block and surface is 0.35, what was the original speed of the bullet?

5. A bullet of mass m-0.02 kg was horizontally shot into a wood block of mass mo 8.98 kg, which is attached at one end of a spring with a spring constant k = 100 N/m, as shown in right Figure. After the bullet was embedded into the wood block, the spring was compressed 10 cm. If the coefficient of kinetic friction is 0.2 between the wood block and the surface, find the initial velocity of the bullet. (10 points)
A bullet of mass 4.3 g is fired horizontally into a 7.4 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.53. The bullet stops in the block, which slides straight ahead for 1.7 m (without rotation). (a) What is the speed of the block immediately after the bullet stops relative to it? (b) At what speed is the bullet fired?
A bullet of mass 7.00 g is fired horizontally into a wooden block of mass 1.20 kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.250. The bullet remains embedded in the block, which is observed to slide a distance 0.300 m along the surface before stopping. a) What was the initial speed of the bullet?
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 0.0260 kg bullet moving horizontally at 450 m/s embeds itself into an initially stationary 0.500 kg block (a) What is their velocity just after the collision? m/s (b) The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.30 kinetic coefficient of friction. Now what is its velocity? my's (c) The bullet embedded block now strikes and sticks to a stationary 2.00 kg block. How far does this combination travel before stopping? חח Additional Materials Reading
