A bullet of mass 0.006 kg moving at 303 m/s impacts a large fixed block of wood and travels 1 m before coming to rest. Assuming that the acceleration of the bullet is constant, find the magnitude of the resistive force exerted by the wood on the bullet. Answer in units of N and round to one decimal place.

A bullet of mass 0.0018 kg moving at 472 m/s embeds itself in a large fixed piece of wood and travels 0.61 m before coming to rest. Assume that the deceleration of the bullet is constant. 1. What force is exerted by the wood on the bullet? F =
A 7.80 g bullet is initially moving at 540 m/s just before it penetrates a block of wood to a depth of 6.60 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the block of wood? Use work and energy considerations to obtain your answer. (b) Assuming the frictional force is constant, how much time (in s) elapses between the moment the bullet enters the...
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 7.80 g bullet is initially moving at 560 m/s just before it penetrates a block of solid rubber to a depth of 6.30 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the block of solid rubber?

1. A bullet of mass m -25.0 g is fired into a stationary block of mass m, -4.00 kg, which is suspended on a rope, as shown below. The bullet is initially traveling with velocity v. - 400 m/s, passes through the block and emerges with a final velocity horizontally Immediately after the impact the block travels upward with a velocity of 2.00 m's and reaches a vertical height, h before coming to rest. Determine the maximum height the block...
A bullet (0.1 kg) initially moving at speed u is embedded inside block 1 (4 kg) initially at rest at A which travels 8 m in a rough region (uk = 0.2) to B at speed of 12 m/s, then travels to a frictionless region from B to C, then to a rough region (Uk = 0.2) after point C. Then bulletblock 1 collides with block 2 (15 kg) which is initially at rest and connected with a spring of...
26) In Figure 8.4, a bullet of mass 0.01 kg moving horizontally strikes a block of wood of which is suspended as a pendulum. The bullet lodges in the wood, and together they swing upward a distance of 0.40 m. What was the velocity of the bullet just before it struck the wooden block? The length of thestringis2 meters.

QUESTION 7 A bullet of mass 40.0 g moving with a speed of 249 m/s strikes a block of wood of mass 2.00 kg and becomes imbedded in it (stuck inside it). The block had been originally at rest and is free to move. What is the speed of the block and bullet immediately after the collision, in units of m/s? QUESTION 10 If an object is initially at rest and then 'explodes' into two separate pieces, what do we...
