A 1.65-kg falcon catches a 0.375-kg dove from behind in midair. What is their velocity after impact if the falcon’s velocity is initially 26.5 m/s and the dove’s speed is 6.55 m/s in the same direction?

A 3.45 kg black ball traveling 4 m/s has a head on collision with a white one at rest. Using the velocities shown, calculate the mass of the white ball, Ignore friction and air resistance. 0 m/s 4 m/s 1.4 m/s 5.7 m/s

A man that weights 93kg sits on a 210 kg boat. After deciding he wants to stay at his current location with his boat motionless, he throws an anchor that weights 32 kg horizontally with the speed of 4.4m/s. Assume there is no resistance from the water. What is the velocity of the boat with man after the anchor was thrown? draw a picture round significant figures show work

In an attempt to imitate Miley, Betty White launches herself onto a wrecking ball. If she is moving at 6 m/s when she jumps on the ball, how high does the ball swing? Assume: mbetty = 60 kg (~140 lbs) 450 kg (~1000 Ibs) Mball And that the initial velocity is purely in the horizontal direction, and the support chain of the wrecking ball has negligible mass. a) Solve for the maximum swing height symbolically b) Solve for the maximum swing height numerically c) If the wrecking ball support chain has a length of 5 meters, what angular displacement does the ball have from vertical at the highest point?

A 0.19kg baseball is pitched at 42m/s is struck by the bat with an average force of 700 N, which results in a velocity of 28m/s in the opposite direction from the original velocity. How long were the bat and ball in contact?

Calculate the final speed (in m/s) of a 100 kg rugby player who is initially running at 7.50 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.65 x 10* N for 7.50 x 10 -2 S. m/s

A 105-kg rugby player is initially running at 7.5 m/s in the positive direction, but collides head-on with a padded goalpost and experiences a backward force of 1.76 × 104 N for 5.55 × 10–2 s. Calculate the final velocity in the horizontal direction of the rugby player, in meters per second.   vf =

with what force will 1055 kg car that is accelerating at 2.44 m/s/s hit a tree?

A 43kg is standing near and to the left of a 54kg boy, both on frictionless stationary skate boards. The boy throws a .85 kg bag at 7.1 m/s. What is the velocity of the boy after he releases the bag?  What is the velocity of the girl after she catches the bag?

3. Bob and Linda are sweethearts that enjoy skating arm in arm. Bob has a mass of 85 kg and Linda has a mass of 60 kg. Initially they are skating together with a speed of 3.0 m/s. Then Bob whispers a dirty joke into Linda's ear, causing her to push him in the oppposite direction of their motion. If Bob's final speed is 1.0 m/s, what is Linda's final speed? Before: Vi After: VBÍ
