Two ice skaters, 50-kg and 60-kg respectively, moving together at a speed of 2.0 m/s push off against one another. The 50-kg skater acquires a speed of 0.375 m/s. a) What speed does the 60-kg skater acquire? b) What is the impulse on the 50 kg skater

A 190-gram softball pitched at 22 m/s (horizontally) batted on a horizontal line drive back to the pitcher at 34 m/s. a.) How large is the magnitude of the impulse imparted to the ball by the bat? b.)The bat contacts the ball during a time of 5.6 ms. What magnitude average force did the ball experience?

A ball of mass 0.160 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.870 m. What impulse was given to the ball by the floor? magnitude direction

During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.144 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 14.9 m/s, shatters the glass as it passes through, and leaves the window at 11.9 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball? A) opposite the direction of the ball's motion B) neither of these C) in the direction of the ball's motion   Calculate the magnitude of this impulse (a positive number) in N*s.   The ball is in contact with the glass for 0.0102 s0.0102 s as it passes through. Find the magnitude of the average force of the glass on the ball (a positive number). calculate the average force in N.

A ball of mass 0.165 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.920 m. What impulse was given to the ball by the floor? kg-m/s

Question Three

24.A 2.4 kg ball drops vertically onto a floor, hitting with a speed of 25 m/s. It rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during the contact?(b) If the ball is in contact with the floor for 0.020 s, what is the magnitude of the average force on the floor from the ball? a. 42 kg m/s, 2100N b. 84 kg m/s, 4200N c. 84 kg m/s, 2100N d.42 kg m/s, 4200N

Options: A) The lighter cart experiences the larger impulse. B) Both carts experience the same impulse. C) The heavier cart experiences the larger impulse. D) The answer cannot be determined.

@ULM E My Courses This Course Ha E7.A 75-kg front-seat passenger in a car moving initially with a speed of 23 m/s (50 MPH) is brought to rest by an air bag in a time of 0.3 s. What is the impulse acting on the passenger? E8.A ball traveling with an initial momentum of 1.7 kg-m/s bounces off a wall and comes back in the opposite direction with a momentum of -1.7 kg-m/s. What is the change in momentum of the ball? E9.A ball traveling with an initial momentum of 5.1 kg-m/s bounces off a wall and comes back in the opposite direction with a momentum of -4.3 kg-m/s. What impulse is required to produce this change? E11.An ice skater with a mass of 70 kg pushes off against a second skater with a mass of 30 kg. Both skaters are initially at rest. (a) What is the total momentum of the system after they push off? (b) If the larger skater moves off with a speed of 2.8 m/s, what is the corresponding speed of the smaller skater? E12.A rifle with a mass of 3.4 kg fires a bullet with a mass of 7.8 g…

An air track glider is moving along at a steady speed of 3.60 m/s when a force of 1.20 N is applied in the direction opposite to the motion of the glider for a time of 2.40 s. The force then steadily decreases at a rate of 0.60 N/s for the next 3.00 seconds. a. Find the total impulse b. the final speed of the 250-g glider.
