An object thrown upward reaches the highest point in 5 sec. Find the velocity with which it was thrown? (Take g = 9.8 m/s2 )

A body is thrown vertically upwards and rises to a height of 10m. The velocity with which the body was thrown is (g - 9.8m/( s^(2) )

A ball thrown vertically upwards returns to the thrower in 20 second. Calculate the velocity with which it was thrown and the maximum height attained by the ball. Take g = 10 m//s^(2) .

An object is thrown vertically upwards and rises to a height of 10 m. Calculate (i) the velocity with which the object was thrown upwards and (ii) the time taken by the object to reach the highest point.

A parojectile thrown from platform at a height 10 m above the gorund with velocity of 20m//sec . At what angle should the projectile be thrown to reach the frathest point form O , which is vertcally below the point from which it is thrown. [g = 10m//s^(2)]

A body is thrown horizontal from the top of a tower and strikes the ground after two seconds at angle of 45^(@) with the horizontal. Find the height of the tower and the speed with which the body was thrown. Take g = 9.8 ms^(-2) .
