Question

predict the range of the projectile when the ball is released on the inclined plane that makes an angle of 70 degrees with horizontal. support your prediction.

Answer 1

you can do this by
i suppose you know how to solve simple projectile
so first you have to calculate time of flight by
uy=gcos 70 t
time of flight T= 2t
now you can calculate range by formula
R= uxT -(gsin70 T^2)/2

Answer 2

thank you :)
