Homework Help: Science :)

Posted by Sandy on Thursday, October 28, 2010 at 7:39pm.

A football is kicked from the ground at 27 m/s at an angle of 42 degrees above the horizontal (ground). No one gets in the way until after it hits the ground. Use the value g=9.8 m/s^2. Assuming that the ground is level and that there is negligible air resistance, wind, etc.

a)What is the displacement of the ball (distance and direction) 1.0 s after the ball is kicked?

b)What is the velocity of the ball (speed and direction) 1.0 s after the ball is kicked?
