On a flat field, a ball is kicked and given an initial velocity of 28 m/s at an angle of 20 degrees above the horizontal. -What are the x and y components of the ball’s initial velocity?
-From the moment it is kicked, how long will it take for the ball to reach its maximum height?
-What is the maximum height of the ball?
-Find the horizontal distance between the point at which the ball was kicked and the point where it lands.

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
