An object start sliding on a frictionless inclined plane and from same height another object start falling freely

Both will reach with same speed

Both will reach with same acceleration

Both will reach in same time

None of above

Solution

(a)Here the potential energy will be converted to kinetic energy. Initially both the bodies have same potential energy. So finally both the bodies will have same kinetic energy.

$\Rightarrow$ So they will reach the ground with same speed.

Physics

A ball is thrown up vertically with a certain velocity so that, it reaches a maximum height $h$. Find the ratio of the times in which it is at height $\frac{ h }{3}$ while going up and coming down respectively.

Two balls $A$ and $B$ are thrown with same velocity $u$ from the top of a tower. Ball $A$ is thrown vertically upwards and the ball $B$ is thrown vertically downwards. If $t_A = 6\ s$ and $t_B = 2\ s$ then velocity $u$ of each ball is…….$ms^{^{-1}}$

A body projected vertically upwards with a certain speed from the top of a tower reaches the ground in $t_1$. If it is projected vertically downwards from the same point with the same speed, it reaches the ground in $t_2$. Time required to reach the ground, if it is dropped from the top of the tower, is:
