Answer:
The distance by the ball clear the crossbar is 1.15 m
Explanation:
Given that,
Distance = 44 m
Speed = 24 m/s
Angle = 31°
Height = 3.05 m
We need to calculate the horizontal velocity
Using formula of horizontal velocity
Put the value into the formula
We need to calculate the vertical velocity
Using formula of vertical velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
We need to calculate the vertical height
Using equation of motion
Put the value into the formula
We need to calculate the distance by the ball clear the crossbar
Using formula for vertical distance
Put the value of h
Hence, The distance by the ball clear the crossbar is 1.15 m
