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)

विकल्प

• `20sqrt2` m/s, 0

• `20sqrt2` m/s, 10 m/s² 

• 20 m/s, 5 m/s² 

• 20 m/s, 0

Answer 1

`20sqrt2` m/s, 10 m/s²
