Answer:
the range or the ball is 48.81 m
Explanation:
given;
Nicole throws a ball at 25 m/s at an angle of 60 degrees abound the horizontal.
find:
What is the range of the ball?
solution:
let Ф = 25°
Vo = 25 m/s
consider x-motion using time of fight: x = Vox * t
where x = R = range
t = 2 Voy
g
R = Vo² sin (2Ф)
g
plugin values into the formula:
R = (25)² sin (2*25)
9.81
R = 48.81 m
therefore, the range or the ball is 48.81 m
4.8miliseconds broooo.
