The mass of a dog is 35.8 kg. The dog runs into a bouncy wall at 10.0 m/s and bounces back in the opposite direction at 1.75 m/s. What is the magnitude of the dog's impulse n kgm/s?

A golf ball m = 0.11 kg strikes a vertical concrete wall elastically with a horizontal velocity of v = 13 m/s.  Write an expression for the magnitude of the impulse I experienced by the ball. If the ball was in contact with the wall for t = .1s, what is the magnitude of the force F the ball experienced in N? If the ball rebounds with only half the velocity it comes in with, what is the magnitude of the impulse in kg m/s? Determine the magnitude of the change in kinetic energy in the above situation. Give your answer in joules.

A ball falls from height of 20.0 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that m ball = 0.385 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? magnitude x direction 979.1 Assume the only impulse delivered to the ball is from the floor, which equals the change in momentum of the ball. Find the initial and final speeds of the ball using conservation of mechanical energy, and calculate Ap noting that all the motion is in the y-direction. kg. m/s up ✓✓ (b) If the ball is in contact with the floor for 0.0300 seconds, what is the average force (in N) the floor exerts on the ball? magnitude 19.223 x Use the impulse-momentum theorem and the result from part (a) to find the force, given that the contact time interval is 0.0300 s. N up direction ✓✓

A(n) 0.5 kg softball is pitched at a speed of 17 m/s. The batter hits it back directly at the pitcher at a speed of 25 m/s. The bat acts on the ball for 0.012s. What is the magnitude of the impulse imparted by the bat to the ball?Answer in units of N · s. What is the magnitude of the average force exerted by the bat on the ball?Answer in units of N.

A hockey player strikes a puck that is initially at rest. The force exerted by the stick on the puck is 967 N, and the stick is in contact with the puck for 4.2 ms (0.0042 s).  how do you find the impulse imparted by the stick to the puck. kg · m/sand , What is the speed of the puck  just after it leaves the hockey stick? mass of puck is 1.65kg m/s

Two rams are fighting and run straight at each other. Ram 1 has m1 = 115 kg and an initial velocity v1 = 9 m/s. Ram 2 has m2 = 127 kg and an initial velocity v2 = -7 m/s. When they collide, they lock horns.  What impulse did Ram 2 deliver to Ram 1?

A soccer ball with a mass of 0.427 kg approaches a player horizontally with a speed of 14.0 m/s. The player kicks the ball with her foot, which causes the ball to move in the opposite direction with a speed of 22.3 m/s. (a) What magnitude of impulse (in kg · m/s) is delivered to the ball by the player?  kg · m/s   (b)What is the direction of the impulse delivered to the ball by the player? - In the same direction as the ball's initial velocity  - Opposite to the ball's initial velocity       - Perpendicular to the ball's initial velocity  - The magnitude is zero.   (c) If the player's foot is in contact with the ball for 0.0600 s, what is the magnitude of the average force (in N) exerted on the player's foot by the ball?

A force of 90.0 newtons is applied to a cart traveling at 15.0 meters per second. After the force has been applied for 2.00 seconds, it comes to rest. What is the magnitude of the impulse applied to the cart over these 2.00 seconds?

A stone is dropped from a height of h1 = 3.55 m above the ground. After it bounces, it only makes it to a height h2 = 2.37 m above the ground. The stone has mass m = 0.148 kg.  a) What is the magnitude of the impulse I, in kilogram meters per second, the stone experienced during the bounce?   b)  If the stone was in contact with the ground for t = 0.153 s, what was the magnitude of the constant force F acting on it, in newtons?   c) How much energy, in joules, did the stone transfer to the environment during the bounce?
