An open lift is moving upwards with velocity 10 m/s . It has an upward acceleration of 2 m/s2 . A ball is projected upwards with velocity 20 m/s relative to ground. Find
Take g=10 m/s2
(a) time when ball again meets the lift
(b) displacement of lift and ball at that instant.
(c) distance travelled by the ball upto that instant.
