A jet plane is cruising at 300 m/s when suddenly the pilot turns the engines up to full throttle. After traveling 4.0 km, the jet is moving at a speed of 400 m/s. What is the jet’s acceleration, assuming it to be a constant acceleration?

Short Answer

Expert verified

The acceleration of the plane is8.75ms2.

Step by step solution

01

Given information

The initial speed of a plane is vis=300ms

Distance covered by plane is s=4km=4000m

The final speed of the plane isvfs=400ms

02

The acceleration of the plane.

Use kinematical equation v2fs=v2is+2as.

Substitute known values

4002=3002+2a40004002-3002=8000aa=700008000=8.75ms2

Therefore, the acceleration of the plane is8.75ms2.

A rubber ball is shot straight up from the ground with speed v0. Simultaneously, a second rubber ball at a height h directly above the first ball is dropped from rest.
a. At what height above the ground do the balls collide? Your answer will be an algebraic expression in terms of h, v0, and g.
b. What is the maximum value of h for which a collision occurs before the first ball falls back to the ground?
c. For what value of h does the collision occur at the instant when the first ball is at its highest point?
