A ball is thrown at angle `alpha( 90^(@)gtalphagttheta)` on inclination plan as shown in figure. The minimum speed of the ball during the motion is:

What happens to the speed of the ball during its downward motion ?

A ball is projected from point A with velocity 10 ms^(-1) perpendicular to the inclined plane as shown in figure. Range of the ball on the inclined plane is

A ball is projected from point A with velocity 20 m/s prependicular to the inclined plane as shown in figure. What is the range of the ball on the inclined plane ?

A ball is projected from point A with velocity 10 ms^(-1) perpendicular to the inclined plane as shown in figure. Range of the ball on the inclined plane is

A ball is thown at angle theta and another ball is thrown at angle (90^(@)- theta) with the horizontal direction from the same point each with speeds of 40 m/s. The second ball reaches 50 m higher than the first ball. Find the individual heights. g= 10 m//s^(2)
