Fred is playing baseball with his friends in a vacant lot. fred hits the ball at an angle of 40 degrees (at a height of 1.0m) and it crashes through the 3.4m high window of mr. jenkins house 67m away. what speed did fred give to the ball

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.

which statement about this sum is true? −245+2.7

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
