Afootball is thrown at an angle of 44◦ above the horizontal. assume the ball is throw and received at the same height. to throw a 55.7 m pass, what must be the initial speed of the ball? the acceleration due to gravity is 9.8 m/s 2 . answer in units of m/s.

The initial speed of the ball is 23.3 m/s.

Explanation:

Given that,

Angle = 44°

Range = 55.7 m

We need to calculate the initial speed of the ball

Using formula of range

Where. u = initial velocity

r = range

g = acceleration due to gravity

Put the value into the formula

Hence, The initial speed of the ball is 23.3 m/s.

i. like it i'm gonna edit it tomorrow

are there answer choices to this question? this seems like a question where you have options to choose from.
