A ball of mass 0.180 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.785 m. What impulse was given to the ball by the floor? Magnitude
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 0.820 m. What impulse was given to the ball by the floor? magnitude kg. m/s direction

A 0.600-kg ball is dropped from rest at a point 4.50 m above the floor. The ball rebounds straight upward to a height of 3.40 m. Taking the negative direction to be downward, what is the impulse of the net force applied to the ball during the collision with the floor?
A 0.580-kg ball is dropped from rest at a point 4.30 m above the floor. The ball rebounds straight upward to a height of 2.30 m. Taking the negative direction to be downward, what is the impulse of the net force applied to the ball during the collision with the floor?
Need Help?Read 9.。)-12 points SerCP9 6P027 wi A 69.0-kg person throws a 0.0420-kg snowball forward with a ground speed of 31.0 m/s. A second person, with a mass of 55.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.00 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and...
INCREASING TIME > 6) Consider a ball that is dropped from rest from a height of 1.0 meter above the floor. It starts at rest, then speeds up, suddenly reverses direction, and then slows as it rises. Suppose it bounces off the floor and rises back up to a height of 1.0 m (it is a super super- ball). Sketch x, y, vr, and Vy vs. time graphs of this motion (on a separate sheet ofpaper), as illustrated in the...
6. A 50-kg front seat passenger in a car moving initially with a speed of 25 m/sisbr rest by an air bag in a time of 0.4 s a) What is the impulse acting on the passenger? b) What is the average force acting on the passenger in this process?? 7. A ball traveling with an initial momentum of 5.0 kg.m/s bounces off a wall and comes back in the opposite direction with a momentum of -4.5 kg.m/s a) What...
2. Two steel balls are colliding elastically. Ball 1 has a mass of 1.20 kg and is moving 3.00 m/s at an angle of 45 degrees measured from the positive X-axis before the collision. Ball 2 has a mass of 1.50 kg and is moving 2.50 m/s at an angle of 60 degrees above the negative X- axis before the collision. Assume the balls hit squarely without a glancing blow so the balls can roll in the direction calculated normally....
A 0.2 Kg ball is dropped with no initial velocity from a height of 6 m. It drops vertically with no air drag, it hits the flat, concrete ground and re-bounces upward in a vertical direction reaching a maximum height of 4 m. (i) Calculate the speed of the ball when it hit the ground. (ii) Calculate the speed of the ball when it began moving upward. (iii) Calculate the magnitude of the impulse provided by the ground to the...
