Explanation:
Answer:
Speed, v = 26.5 m/s
Explanation:
It is given that,
The ball hits the ball at an angle of 40 degrees.
Initial height of the ball, h = 1 m
Vertical distance, y = 3.4 m
Horizontal distance, x = 67 m
The trajectory of the particle in projectile motion is given by :
R is the range of projectile.
Putting all the values in above equation as :
R = 71.3 meters
Now using the formula of the range of the projectile as :
Substituting the values in above equation as :
u = 26.5 m/s
So, the speed with which Fred give to the ball is 26.5 m/s. Hence, this is the required solution.
