A:
A 28-g steel-jacketed bullet is fired with a velocity of 650 m/s toward a steel plate and ricochets along path CD with a velocity of 500 m/s. Knowing that the bullet leaves a 50-mm scratch on the surface of the plate and assuming that it has an average speed of 600 m/s while in contact with the plate, determine the magnitude and direction of the impulsive force exerted by the plate on the bullet.

- A 250-g golf club head moving horizontally at 24.2 m/s strikes a stationary 45.7−g ball. The ball comes off the club moving in the club's initial direction at 37.6 m/s. Find the club head's speed immediately after contact. (Assume there's no additional force from the golfer.)Two spheres collide on a horizontal surface (all velocities, before and after the collision, are in the x-y plane). Throughout this problem, assume that all forces aside from those exerted by the spheres themselves are negligible (at least in comparison). Sphere A has a mass of 0.65 grams. It has an initial speed of 6.0 m/s and an initial velocity that is oriented at an angle of θ A i = 28 degrees below the x-axis. Sphere B has a mass of 0.45 grams. It has an initial speed of 6.5 m/s and an initial velocity that is oriented at an angle of θ B i = 35 degrees above the x-axis. After the collision, sphere A has a speed of 3.5 m/s and a velocity that is directed at an angle of θ A f = 16 degrees above the x-axis. What is the final speed, in units of meters per second, of sphere B?In the figure, block 1 of mass m₁ slides from rest along a frictionless ramp from height h-3 m and then collides with stationary block 2, which has mass m₂ - 5m₁.

What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? (a) Number (b) Number i h Unit Unit Frictionless 9 -H₂

Assuming perfectly elastic impact (e= 1) and no friction, determine the height h reached by ball B.A 80.1 kg linebacker (X) is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7 kg running back (O) moving at 9.49 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?f of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?In the figure, block 1 of mass m₁ slides from rest along a frictionless ramp from height h=2.5 m and then collides with stationary block 2, which has mass m2 = 3m₁.

(a) What is the speed and direction of the other piece after the explosion? Be sure to explain how you are able to determine this. (b) Compare the kinetic energy of the single object before the explosion to the total ki- netic energy of the two pieces after the explosion. Explain how this relates to the term 'explosion'.One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint.

The car passes under a loading chute and, as it does so, gravel falls vertically into it for 2.792.79 s at the rate of 475 kg/s. What is the car's speed vf after the loading is completed? Ignore rolling friction.A baseball player pitches a fastball toward home plate at a speed of 41.0 m/s. The batter swings, connects with the ball of mass 290 g, and hits it so that the ball leaves the bat with a speed of 37.0 m/s. Assume that the ball is moving horizontally just before and just after the collision with the bat. If the bat and ball are in contact for 3.00 ms, what is the magnitude of the average force exerted on the ball by the bat? answer in knA 28-g bullet moving horizontally strikes and remains in a 2.6-kg block initially at rest on the edge of a table.
