Two fixed frictionless inclined planes m...

Two fixed frictionless inclined planes making angles 30° and 60° with the vertical are shows in the figure. Two blocks A and B are placed on the two planes. What is the relative vertical acceleration of A with respect to B ?

Text Solution

Verified by Experts

Horizontal range, `R=(u^(2) sin 2 theta)/(g) rArr (u^(2) sin 60^(@))/(g) rArr (u^(2))/(g)=2sqrt3`
Since the muzzle velocity is fixed. Therefore, maximum horizontal range `R_(max)=(u^(2))/(g)=2sqrt3=3.46 m,` So, the bullet cannot hit the target.
