Tom kicks a soccer ball on a flat, level field giving it an initial speed of 20 m/s at an angle of 35 degrees above the horizontal. a) how long will the ball be in the air? b) what maximum height will the ball attain? c) how far away from tom will the ball land? d) what speed will the ball have in the instant just before it lands?

(a) 2.34 s

(b) 6.71 m

(c) 38.35 m

(d) 20 m/s

Explanation:

u = 20 m/s, theta = 35 degree

(a) The formula for the time of flight is given by

T = 2.34 second

(b) The formula for the maximum height is given by

H  = 6.71 m

(c) The formula for the range is given by

R = 38.35 m

(d) It hits with the same speed at the initial speed.
