The fiqure below shows a steel ball with a mass of 3.04 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v = 10.0 m/s), and the angle its path makes with the wall is e = 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after impact, you may safely ignore the effect of gravity on the ball.) The ball is in contact with the wall for 0.196 s. What is the average force (in N) exerted by the wall on the ball during the impact? magnitude N direction -Select--

In your job in a police lab, you must design an apparatus to measure the muzzle velocities of bullets fired from handguns. Your solution is to attach a 2.00 kgkg wood block that rests on a horizontal surface to a light horizontal spring. The other end of the spring is attached to a wall. Initially the spring is at its equilibrium length. A bullet is fired horizontally into the block and remains embedded in it. After the bullet strikes the block, the block compresses the spring a maximum distance dd. You have measured that the coefficient of kinetic friction between the block and the horizontal surface is 0.38. The table below lists some firearms that you will test.

Block A has a mass mA and is attached to a spring having a stiffness k and an unstretched length l0. If another block B, having a mass mB, is pressed against A so that the spring deforms a distance d, determine the distance both blocks slide on the smooth surface before they begin to separate. What is their velocity at this instance?
You have been asked to design a "ballistic spring system" to measure the speed of bullets. A bullet of mass m is fired into a block of mass M. The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is k. The opposite end of the spring is anchored to a wall. The spring's maximum compression d is measured.What was the speed of a 2.1 g bullet if the block's mass is 1.5 kg and if the spring, with k = 40 N/m , was compressed by 15 cm ?

The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is k. The opposite end of the spring is anchored to a wall.

A physics lab instructor is working on a new demonstration. She attaches two identical copper balls with mass m = 0.180 g to threads of length L as shown in the figure. There are two strings in the figure. The top of each string is connected to the ceiling, and both strings are connected at the same point. The bottom of each string is connected to a spherical mass labeled m. Both strings have length L and hang at an angle of ? to the vertical, with the two strings on opposite sides of the vertical. Both balls have the same charge of 7.60 nC, and are in static equilibrium when ? = 4.75°. What is L (in m)? Assume the threads are massless. m (b) What If? The charge on both balls is increased until each thread makes an angle of ? = 9.50° with the vertical. If both balls have the same electric charge, what is the charge (in nC) on each ball in this case?
A 0.430 kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 26.0 N/m force constant that is at its equilibrium length. A 0.0600 kg wad of Play-Doh is thrown horizontally at the block with a speed of 2.60 m/s and sticks to it. Determine the amount in centimeters by which the Play-Doh-block system compresses the spring.
There is a pendulum on a very long, light, string. The bob is made entirely of play-do and weighs 19.90 kg. It sits motionless directly below its point of support. A 100 g bullet is fired at the bob and strikes it with a velocity of 200 m/s. Although the bob is badly deformed, it remains one piece with the bullet embedded deep within it. The bob/bullet swing attaining a maximum height of h. Calculate h.
A steel shotgun with a mass of 3 kg hits a large wall at an angle of 60 ° with the wall at 10 m / s and the ball is reflected at the same speed and angle. If the ball is in contact with the wall for 0.2 s, what is the force the wall exerts on the ball? (sin60 ° = 0.87 and cos60 ° = 0.5)(G = 10)
A block of mass m2 = 10.0 kg, at rest on a horizontal surface that has negligible friction, is connected to a spring which is initially not stretched or compressed. The other end of the spring is fixed to a wall, and the spring constant is k = 90 N/m. Another block of mass m1 = 14.0 kg and speed v1 = 3.2 m/s collides with the 10.0 kg block. The blocks stick together, and compress the spring. What is the maximum compression of the spring?
Each of the two elastic rubber bands of the slingshot has an unstretched length of 200 mm. If they are pulled back to the position shown and released from rest, determine the maximum height the 25-g pellet will reach if it is fired vertically upward. Neglect the mass of the rubber bands and the change in elevation of the pellet while it is constrained by the rubber bands. Each rubber band has a stiffness k = 50 N/m.
A bullet with a mass m(b)=13.1 g is fired into a block of wood at velocity v(b)=261 m/s. The block is attached to a spring that has a spring constant k of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cmbefore the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass m(w) of the wooden block.
