During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of 10.0 kg and the horizontal component of its velocity is 8.00 m/s when the 65.0-kg performer catches it. If the performer is on nearly frictionless roller skates, what is his recoil velocity?
A propane tank explodes into three pieces of equal mass. After the explosion, one of the masses has a velocity of 10 m/s [S]. If a second mass moves at a velocity of 6.0 m/s [N 50o W], what is the velocity of the third mass?
A 3kg mass is traveling south at 15 m/s when it experiences a perfectly inelastic collision with a 2 kg mass that was headed east at 17 m/s. What is is final velocity of the two masses along with the magnitude and direction of both.
Two masses undergo a collision and they stick together. M1 has a mass of 550g and was traveling at an unknown velocity toward the second mass, M2=400g, which was traveling in the same direction at 4.5m/s. After the collision, they have a velocity of 5.1 m/s. Determine the velocity of the first mass before the collision.
Astronomers estimate that a 2.0-km-diameter asteroid collideswith the Earth once every million years. The collision couldpose a threat to life on Earth. (a) Assume a spherical asteroidhas a mass of 3200 kg for each cubic meter of volume andmoves toward the Earth at 15 km/s How much destructiveenergy could be released when it embeds itself in the Earth?(b) For comparison, a nuclear bomb could release about 4.0x1016 JHow many such bombs would have to explodesimultaneously to release the destructive energy of theasteroid collision with the Earth?
A mass mA = 50 kg moving with a velocity vA = (5.0i + 2.0j – 4.0k) m/s, collides with mass mB = 5.0 kg which is initially at rest. Immediately after the collision, mass mA is observed traveling at velocity (-3.0i - 2.0k) m/s. Calculate the magnitudes of vA and vA’. the velocity of B after impact (vB’}.
A 7.5-kg rock flying through the air is traveling at a velocity of 12m/s when it collides into and sticks to a stationary bean bag, weighing 22.5-kg. What is the velocity of the two objects?
Two masses undergo a collision and they stick together. M1 has a mass of 550g and was traveling at and unknown velocity toward the second mass, M2=400g, which was traveling in the same direction at 4.5m/s. After the collision, they have a velocity of 5.1m/s. Determine the velocity of the first mass and before the collision.
The rocket takes off from Earth and reaches a speed of 130 m/s in 13.0 s. If the exhaust speed is 1,600 m/s and the mass of fuel burned is 120 kg, what was the initial mass (in kg, including the initial fuel) of the rocket?
A pickup truck has a mass of 874.05kg. It travels with a velocity of 21.361m/s before it hits a deer, at rest, standing in the middle of the road. They then travel together with a velocity of 17.342m/s. What is the mass of the deer?
Two object again undergo a collision but totally bounce off this time. M1 with a mass of 400g traveling at 10m/s to the right strikes a stationary mass of 560g. What is the velocity of the mass after the collision and in which direction?
A 1.00-kg duck is flying overhead at 1.50 m/s when a hunter fires straight up. The 0.010 0-kg bullet is moving 100 m/s when it hits the duck and stays lodged in the duck’s body. What is the speed of the duck and bullet immediately after the hit?
