A ball thrown up vertically returns to the thrower after 6
find
a. The velocity with which it was thrown up,

Text Solution

Verified by Experts

a. u = 0, v = 0, g -9.8 m/`s^(2)`
Total time taken = 6 sec (up + down )
Time for upward journey = `(6)/(2)` = 3s
v = u + `"gt"^(2)`
0 = u + (-9.8) `xx` 3
u = 29.4 m/s
