Question

A projectile is fired with an initial speed of 33 m/s at an angle of 45 above the horizontal. The object hits the ground 10 s later.

How much higher or lower is the launch point relative to the point where the projectile hits the ground? Use positive sign if the launch point is higher and negative if the launch point is lower.
Express your answer to two significant figures and include the appropriate units.

To what maximum height above the launch point does the projectile rise?
Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Y = vtsin? - 1.2gt^2 = -256.65.Therefore , the launch point relative to the point where the projectile hits the ground is below 256.65 m. H = v^2sin?^2/2g = 27.78 m
