A batter hits a baseball so that it leaves the bat with an initial speed 37 m/s at an angle of 53.what will be the position of the ball and the magnitude and direction of its velocity after 2 seconds?Treat the baseball as a projectile.
1 Answer
As,we know,in case of a projectile motion,the projectile moves forward with its constant horizontal component of velocity and after going for a certain height due to its vertical component of velocity it reaches back to the ground due to gravity.
So,we can say after
Given,
So,
And horizontal displacement will be
So,after
Now,let the vertical component of velocity will become
So,
or,
And,horizontal component of velocity remains constant i.e
So,magnitude of velocity after
Making an angle of
