- 11/16 Calculate Acceleration (2) ways POSSIBLE POINTS: 11.1 Joe started to drive faster when the police turned on the siren. Joe's initial velocity was 10m/s He accelerated to 20m/s in 4 seconds. Determine Joe's acceleration. square m/s/s
- 11/16 Calculate Acceleration (2)ways POSSIBLE PO A 1000 kg car moves at 5m/s then accelerates for 10 seconds until reaching a speed of 100m/s What was the acceleration of the car? square m/s/s
- 11/16 Calculate Acceleration (2) ways An object with a mass of 3.0 kg has a force of 9.0 newtons applied to it. What is the resulting acceleration of the object? square m/s2
- A ball of mass 4m is dropped from rest from a height h=10.0m above the ground, as shown above. It undergoes a perfectly elastic collision with the ground and rebounds. At the instant that the ball rebounds, a small piece of clay of mass m is released from rest from the original height h directly above the ball as shown above on the right. The clay, which is descending , eventually collides with ascending. Assume that g 10m/s^2 air resistance is negligible and the collision process takes negligible time. a. Determine the speed of the ball immediately before it hits the ground. b. Determine the time after the piece of clay is released at which the collision takes place. c. Determine the height above the ground at which the collision takes plac d. Determine the speeds of the ball and the piece of clay immediately bef the collision. e. If the ball and the clay stick together on impact, what is the magnitude and direction of their velocity immediately after the collision?
