During a pair ice skating, a 60-kg female ice skater leaps into the air and is caught by her 70-kg partner who was stationary. a. Assuming negligible friction on ice what is the velocity of the pair if the horizontal velocity of the female skater right before she was caught in the air was 5 m/s? b. What is the total KE before she was caught? What is the total KE after she was caught? c. Knowing that the skaters...
Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
Please answer and show work!! 4) A 1kg object is moving with a velocity of 6 m/s to the right. It collides and sticks to a 2kg object moving with a velocity of 3 m/s in the same direction kinetic energy is lost in the collision? 5) A 2kg mass moving with a velocity of 7 m/s collides elastic ally with a 4kg mass moving in the opposite direction of 4 m/s. The 2 kg mass reversed direction after the...
please answer 3-5 and show each step
2 What will provide the "internal force in the experiment where both carts are intially stationary fc 3. During a perfectly inelastic collision, what % of kinetic energy is conserved if an object of mass 5.0 kg strikes a stationary mass of 20.0 kg? what % will be conserved ir the collision is elastlo instead (same two masses) 5120 4, consider the masses in question #3 and assume an elastic collision between them....
1. A 3000 kg truck travelling at 50 km/hr strikes a stationary 1000 kg car, locking the two vehicles together. A) What is the final velocity of the two vehicles? B) How much of the initial kinetic energy is lost to the collision? 2.What is the gravitational force between two masses of mass 30 lbs and 50 lbs, separated by a distance of 2 meters? 3. Hans Full is pulling on a rope to drag his backpack to school across...
The answers are 23 (D), 28 (A), 30 (A), and 31 (D). Please show
the step by step solution. I need to understand HOW to do these
problems so please only answer if you can help.
Thank you in advance!

4/5 a the minimum kinetic energy at the apping point? (C) Use conservation of energy to determine the minimum angular velocity of the block just after the collision, (d) then use conservation of angular momentum during the collision to find the initial speed of the bullet vo. (Hint: Ignore the mass of the bullet after the collision. The moment of inertia of the cube about its bottom-right edge...
