A student drops a ball from an upstairs window.
Ignore air resistance.
State the acceleration of the ball as it falls.
The ball falls for 1.2 s before it hits the ground.
Calculate the velocity of the ball just before it hits the ground.
The student then drops a feather from the same window.
Explain why the feather takes much longer than the ball to reach the ground.
A car accelerates from rest to 15 m/s in about 6 s.
Estimate the acceleration of the car and compare it with the acceleration of the falling ball.
