You are standing on a skateboard, initially at rest. A friend throws a very heavy ball towards you. You can eithercatch the object or deflect the object back towards your friend (such that it moves away from you with the samespeed as it was originally thrown). What should you do in order to minimize your speed on the skateboard?O No answer text provided.O Catch the ball.Your final speed on the skateboard will be the same regardless whether you catch the ball or deflect the ball.O Deflect the ball.

SERCP11 6.2.P.030. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass m, = 75.0 kg moves in the negative y-direction at 2.50 m/s and skater B with mass m. = 90.0 kg moves in the negative x-direction at 2.00 m/s. Find the x- and y-components of the 80.0 kg skater C's velocity (in m/s) after the push. HINT m/s m/s Need Help? Watch It
Problems 1. A 3.7kg Superball hits the floor with a speed of 6m/s, and it bounces back up into the air with a speed of 4m/s. If the collision takes 0.03s, what is the average normal force of the floor on the ball? You can use the table but you don't have to. 12112 Pf Y •
Dan is gliding on his skateboard at 3.00 m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00 m/s. Dan's mass is 50.0 kg and the skateboard's mass is 7.00 kg.

A small car has a head-on collision with a large truck. Which of the following statements concerning the magnitude of the average force due to the collision is correct? O The small car experiences the greater average force magnitude. The small car and the truck experience the same average force magnitude. O The truck experiences the greater average force magnitude. It is impossible to tell since the masses are not given. It is impossible to tell since the velocities are not given. L _
One block of mass m_1=2.0 kg is sliding down along a frictionless ramp from a height of h=2.5 m. It then collides with another block of mass m_2=1 kg and after the collision the stick together. Then, both of the blocks slide together into a region where the coefficient of kinetic friction is 0.500 and comes to a stop after distance d m within that region. a. Find the velocity of the block of mass m1 at the bottom of the ramp. b. Find the velocity of the two-block at which they slide into the region with kinetic friction coefficient 0.500. c. Find the value of distance d at which they stop

Mechanic Physics: Please make sure this is right #10 In the figure, block 1 of mass m1 slides from rest along a frictionless ramp from height h = 3.4 m and then collides with stationary block 2, which has mass m2 = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction μk is 0.15 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?
Please answer and solve the question correctly. Thank you!
It is a sunny day, and we have decided to do lab outside instead of staying cooped up. Ceylani goes to the top of Jordan Hall, and throws a ball of mass 4.87 kg down from the top of Jordan which is 124 m tall. Her lab partner, Tray, is waiting at the bottom to collect the ball and return it, for more data trials. The ball has a speed of 3.8 m/s when Ceylani throws it straight down. What is the speed of the ball as it reaches the ground? Your Answer: units Answer
A pitcher claims he can throw a 0.148-kg baseball with as much momentum as a 3.28-g bullet moving with a speed of 1.50 x 10³ m/s. (a) What must the baseball's speed be if the pitcher's claim is valid? m/s (b) which has greater kinetic energy, the ball or the bullet? O The bullet has greater kinetic energy. The ball has greater kinetic energy. O Both have the same kinetic energy.
stretch 38. Realizing that he could not drive up a 30°, ice-covered hill because there was no friction, Sir Isaac Newton had stopped his cart, of total mass 500 kg, at the bottom. He was struck in the rear by a London stage coach, of total mass 1500 kg. trav- elling at 20 m/s. The two vehicles stuck together, with nothing breaking loose, and slid up the hill in a straight line. How far up the slope did the wreckage get before coming to rest? (SIN '70)
A baseball is thrown vertically upward and feels no air resistance. It reaches a maximum height and turns back downwards. As it is moving downwards O its gravitational potential energy is not conserved, buts its momentum is conserved. O both its momentum and its kinetic energy are conserved. O its momentum is not conserved, but its mechanical energy is conserved. O its kinetic energy is conserved, but its momentum is not conserved. O both its momentum and its mechanical energy are conserved.
