A ball was dropped from a building and reached the ground in 4s. Show the equations that you use and all calculations. a) How much was the height of the building? b) How fast was it going when it hit the ground? c) How much is the acceleration of the ball (magnitude and direction)? Explain
1. A ball was dropped from a building and reached the ground in 4s. Show the equations that you use and all calculations.
a) How much was the height of the building?
b) How fast was it going when it hit the ground?
c) How much is the acceleration of the ball (magnitude and direction)? Explain
2. A ball is thrown up and it takes 9 seconds to reach maximum height. Show the equation that you use
a) How fast was it going when I threw it?
b) How high up did it go?
d) What was the acceleration (magnitude and direction) of the ball going up? Explain.
e) What was the acceleration (magnitude and direction) of the ball going down? Explain.
f) When was the ball speeding up and slowing down? Explain.
