Motion in a Plane

A car starts from rest and accelerates at $5 m/ s^{2}$ . At $t = 4$ s, a ball is dropped out of a window by a person sitting in the car. What are the velocity and acceleration of the ball at $t = 6$ s? (Take $g = 10 m/ s^{2}$ )

A.20 m/s, $5 m/ s^{2}$
B.20 m/s, 0
C. $202$ m/s, 0
D. $202$ m/s, $10 m/ s^{2}$ ✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
