Question

A projectile is fired horizontally from an inclined plane (of inclination 45° with horizontal) with speed = 50 m/s. If g = 10 m/s², the range measured along the incline is

G1 Physics · Accepted Answer

Let x be horizontal distance and y the downward drop. For horizontal launch, x = 50t and y = 5t². The 45° incline satisfies y = x, so 5t² = 50t and t = 10 s. Thus x = 500 m. Distance along the incline = x sec45° = 500√2 m. Hence option B.
