A 3 kg particle is moving with an initial velocity of 20 m/s to the right when it explodes into two fragments. Immediately after the explosion, which occurs at the origin of the coordinate system, the velocity of fragment A is observed to be 60 m/s and the fragments are traveling in the direction shown. Answer: A) what is the mass of fragment A; B) what is the speed of fragment B.
INITIAL: FINAL: M. A white billiard ball with mass mw = 1.53 kg is moving directly to the right with a speed of v = 3.25 m/s and collides elastically with a black billiard ball with the same mass mb = 1.53 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of ew = 51° and the black ball ends up moving at an angle below the horizontal of Ob = 39°. %3D 1) What is the final speed of the white ball? m/s Submit 2) What is the final speed of the black ball? m/s Submit

A soccer player bounces the ball off her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 8.70 m/s to vfx = 5.10 m/s and the y component from viy = −4.00 m/s to vfy = 2.70 m/s.

A steel ball of mass 0.440 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure.

1. Physics Problem: The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum (see the Figure below). As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, vo, and the maximum height h. Determine the percentage energy loss in the inelastic collision. 2. The ballistic pendulum device will be demonstrated in class. 3. Fire the ballistic pendulum five times and record the pendulum's maximum height after each round. 4. Remove the pendulum arm from the ballistic pendulum. Mass the pendulum arm and the projectile separately. 5. Determine the average speed and the statistical error (standard deviation).

A 17.0 kg body is moving through space in the positive direction of an x-axis with a speed of 180 m/s when it breaks into three parts due to an internal explosion. One part, with a mass of 8.0 kg, moves away from the point of explosion with a speed of 190 m/s in the positive y direction. A second part, with a mass of 5.00 kg, moves in the negative x direction with a speed of 410 m/s. What is y-component of velocity of the third part? (Your result must be in units of m /s. No need decimal place and maximum of 2% of error is accepted in your answer.)
