5. A 0.6 kg ball is dropped with no initial speed from a height of 8 m. The ball bounces off the ground vertically, reaching a height of 7 m. Calculate: (i) The speed of the ball when it hits the ground. (ii) The speed of the ball when it nounces off the ground. (iii) The (magnitude of the) impulse provided by the ground. 6. A 0.2 kg ball hits a bat at 20 m/s and bounces back at 40...
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...
QUESTION 9 10 A cricket bat hits a ball and supplies an impulse of 27.3 Ns to the ball. If the bat and ball were in contact for a time of 0.0565 s, what was the magnitude of the average force that the bat applied to the ball, in units of newtons? Give the answer as a positive number, QUESTION 10 10 pois If an object is initially at rest and then explodes' into two separate pieces, what do we...
