This time, your mass is 75.2 kg and the sled s mass is 10.5 kg. You re on the sled, initially moving to the west at 6.53 cm/s. From the southern shore, your friend throws a baseball of mass 0.132 kg, which you catch as it s traveling northward with a horizontal velocity component of 28.4 m/s. What will be the sled s (and your) speed after catching the ball? 1 6.28 cm/s 7.85 cm/s 4.98 cm/s 4 35.3 cm/s

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.

A BB gun is fired at a cardboard box of mass m2 = 0.75 kg on a frictionless surface. The BB has a mass of m1 = 0.012 kg and travels at a velocity of v1 = 98 m/s. It is observed that the box is moving at a velocity of v2 = 0.26 m/s after the BB passes through it. PART A) what is the BB's final velocity, vf, in meters per second PART B) if the BB doesnt exit the box, what will the final velocity of the box be in meters per second?

A non-BYU Idaho student is having a snow ball fight. 'Accidentally' a snowball travelling north at 10.0 m/s hits a bicyclist traveling west at 5.00 m/s. The mass of the snowball is 0.750 kg, and the bicyclist is 55.0 kg. What is her final velocity, a. If the snow ball sticks to the bicyclist? b. If the snow ball bounces off with a speed of 2.0 m/s at an angle 20.0° West of South?

A bullet of mass 18.4 grams is fired with a speed of 341 meters per second toward a wood block of mass 249 grams initially at rest on a very smooth surface. a. What is the change in momentum of the bullet if it becomes embedded in the block? b. What is the change in momentum of the bullet if it ricochets in the opposite direction with a speed of 330 meters per second?

2. A villain with mass 65.0 kg runs at a velocity of 9.26 m/s directly into Chuck Norris' fist moving at a speed of 0.150 m/s. The villain is knocked back at a velocity of 8.52 m/s and angle 20.0° from the horizontal, while Chuck Norris' fist moves at a velocity of 0.0745 m/s and 10.0° from the horizontal. a. What is the mass of Chuck Norris' fist in kg? b. How much kinetic energy is lost in the collision? Vii † Note: This is a silly problem with silly answers! 20° 10°

A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the gun sliding on the ice in the other direction. The bullet's mass is 0.03 kg, and its speed is 295 m/s. If the gun's mass is 2.5 kg, what is its speed (in m/s)?  m/s

A miniature spring-loaded, radio-controlled gun is mounted on an air puck. The gun’s bullet has a mass of 5.00 g, and the gun and puck have a combined mass of 120 g. With the system initially at rest, the radio controlled trigger releases the bullet causing the puck and empty gun to move with a speed of 0.500 m/s. What is the bullet’s speed? a. 4.80 m/s.        b. 11.5 m/s          c. 48.0 m/s                    d. 12.0 m/s
