Question

Problem 65

Answer 1

Given information

Given the height of the right-field fence,

The initial height of the ball ,  

Angle made by the path with the ground, .

Horizontal distance travelled by the ball,

Step-by-step explanation

Step 1.

Consider the horizontal motion of the ball,

Let, the initial velocity of the ball be . Then the horizontal component of the initial velocity of the ball is, .

In a projectile, there are no horizontal forces acting, and hence the horizontal acceleration is zero. So, we can write;

Substituting the known values and solving for 't', we get;

.
