A bus that is traveling at 33.0 km/h, speeds up at a constant rate of 3.5 m/s2. What velocity does it reach 6.8 s later?
An airplane starts from rest and accelerates at a constant 3.10 m/s2 for 27.0 s before leaving the ground.
(a) How far did it move?
(b) How fast was the airplane going when it took off?
A tennis ball is thrown straight up with an initial speed of 18.5 m/s. It is caught at the same distance above the ground.
(a) How high does the ball rise?
(b) How long does the ball remain in the air? (Hint: The time it takes the ball to rise equals the time it takes to fall.)
