Question

A ball thrown vertically upward returns to the thrower after 6s. The ball is 5m below the highest point at the=2s. The time at which the body will be at same position, g=10m/s².
1. 2.5s
2. 3s
3. 4s
4. 5s

Answer 1

alternate way is

T1 +T2 = Time of flight.
.
where T1 and T2 are the times when ball is at same height.

if in the given question T1 = 2 and time of flight = 6

then 2+T2= 6
.T2 = 4 sec.
