Question

Find at what angle with the horizontal a body should be projected with a velocity of 28m/s so that its horizontal range is 78.4m​

Answer 1

Answer:

In the horizontal direction, the object travels at a constant speed v0 during the flight. The range R (in the horizontal direction) is given as: R=v0⋅T=v0√2Hg R = v 0 ⋅ T = v 0 2 H g .
