Problem 13E
Section 2.4 Motion with Constant Acceleration
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 with a speed of 400 m/s. What is the jet’s acceleration, assuming it to be a constant acceleration?
ANSWER:
Step 1 of 2
We need to find out the jet’s acceleration.
Using Kinematics,
\(v_{f}^{2}=v_{i}^{2}+2 a s\)
Implies,
\(a=\frac{v_{f}^{2}-v_{i}^{2}}{2 s}\)
