A baseball leaves the bat with a speed of 47 m/s and an angle of 45° above the horizontal.A 5.0-m-high fence is located at a horizontal distance of 137 m from the point where the ball is struck.Assuming the ball leaves the bat 1.0 m above ground level,by how much does the ball clear the fence?
A)59.7 m
B)47.7 m

The horizontal and vertical components of the initial velocity are equal due to the 45° angle. Using projectile motion equations, calculate the time to reach the fence and then the vertical position of the ball at that time. Subtract the fence height to find the clearance.
