Question

A car starts from rest and accelerates at 5 m/s². At t = 4 s, a ball is dropped out of a window by a person sitting in the car. What is the velocity and acceleration of the ball at t = 6 s? (Take g = 10 m/s²)

Options

• 20 m/s, 0

• `20sqrt(2)` m/s, 0

• `20sqrt(2)` m/s, 10 m/s²

• 20 m/s, 5 m/s²

Answer 1

`underline(20sqrt(2)  "m""/""s", 10  "m""/""s"^2)`
