A billiard ball moving at 5.20 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.67 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude direction 1.56 × Check the initial and final kinetic energies. You will find that your final kinetic energy is not equal to the initial kinetic energy. m/s ° (with respect to the original line of motion)

A 100-kg particle moves with an initial velocity of (4.0i, - 6.0j) m/s. If its velocity changes to v = (3.0i – 8.0j) m/s by the action of a force, determine The net work done on the particle. What principle would you use to solve this problem? The impulse on the particle. True or False: Impulse is equal to the rate of change of momentum.

Asteroid X, speeding at 100 m/s towards an equally massive but stationary asteroid Y, collides with a glancing blow. After collision, X is deflected 350 from its original direction while Y travels at 450 to the original direction of X. See the before & after picture of the collision below. Assuming total momentum is conserved, find the speed of each asteroid after collision. a.) V = 58.2 m/s, v = 71.8 m/s b.) v = 58.2 m/s, V = 71.8 m/s

A projectile of mass mp 29 g and velocity Vp= 312 i Pi hits a box of mass mg= 8.5 kg moving with a velocity =77 and embeds into it. The box with the projectile continues to slide on a frictionless surface until it reaches a frictionless ramp inclined at an angle 0= 12°. 1. Calculate the velocity of the Projectile-Block system after the collision. V pB %3D 2. Calculate the change of the kinetic energy due to the collision. AK = 3. Is the collision elastic inelastic hmax 4. If the incline is frictionless determine the maximum height h, max the Projectile-Box can reach. h max 5. If the incline had a coefficient of kinetic friction of HK=0.25 which of the following heights would be the most likely outcome (Answer without calculation) 3.296 m 1.514 m 5.077 m
