Question

A ball is thrown with velocity U and angle of projection Theta, such that it experiences a continuous retardation and stops horizontally at 3/4th of the Maximum height after achieving the maximum height.

If retardation is in opposite direction of velocity always Find the value of a

Answer 1

Answer:

After the first collision, the velocity remains same along the surface. Perpendicular to the surface, the direction od velocity reverses and becomes

times. <br> Time to reach at the highest point <br>

<br>

<br> Time to flight ,

<br>

<br> Maximum height ,

<br> Range ,

Answer 2

Summary: In one variable, y = 3 represents a point and in two variables, y = 3 represents a straight line passing through the point (0, 3) and parallel to the x-axis.
