Question

A baseball is hit with an initial speed of 10m/s at an initialangle of 60 deg. Find the balls position, magnitude, and direction of itsvelocity, when t = 1 sec Find the horizontal distance from the starting point to thepoint where the ball hits the ground.
Again, can someone please take me through this problem step bystep, with how to do it and what formulas to use.

Explanation / Answer

initial speed of the ball u = 10 m/s angle of projectile    =60o horizontal distance from the starting point to the pointwhere the ball hits the ground.                       R   = u2 sin 2 / g                             = 102 sin 120   / 9.8                              = 8.83 m position of the ball at t = 1 s       x = u (cos) . t          = 10 ( cos60 ) 1          = 10 * ( 1/2)           = 5 m velocity of the ball at t = 1 s               v = u - gt                    = 10 - 9.8                 =    0.2 m /s
