Question

Two blocks of equal masses are launched upward at the same angle above a horizontal plane. Block A is launched as a projectile. Block B is pushed up alone a fixed incline plane. In the absence of friction and air resistance, which block would reach greater maximum height measured vertically?

TestHub · Accepted Answer

The maximum height of block A is 2 g u 2 sin 2 θ ​ and of block B on the incline is also 2 g u 2 sin 2 θ ​ for the same launch speed u , but the launch speeds are not given. The height depends on the speed of projection, so there is not enough information.
