Solve for Vi:
?x = 1/2(Vi + Vf)?t
(Obligatory velocity review question:)
On the way to school this morning, I was driving 27 m/s. I took my
eyes from the road for exactly 2.0 s to change radio stations. How
far did I travel in that brief interval?
The Concord achieves a lift-off velocity
of 112 m/s in 20.0 s starting from rest. What acceleration is required
to achieve this?
The velocity of a train is 26.4 m/s.
At an average acceleration of -1.50 m/s2, how much time is required for
the train to decrease its velocity to 9.72 m/s?
A basketball player sprints from rest across
the court to 6 m/s in 1.5 s. How far does he travel in that time?
A plane is standing on the runway when the pilot brings the engines to full thrust before releasing the brakes. The aircraft accelerates at 2.9 m/s2 and reaches a takeoff speed of 58 m/s.
a) Find the time from rest to takeoff.
b) Determine the displacement of the plane.
