- Homework Statement
- If a soccer player kicks a ball from the ground with an initial velocity of 15 m/s [30 degrees] above the horizontal] how long does it take the ball to reach its maximum height?

- Relevant Equations
- Vvertical=dsintheta

d=Vvertical*t+0.5atsquared

Vvertical=15sin30

= 7.5m/s

d=Vvertical*t+0.5atsquared

0=(7.5m/s)t+0.5(-9.81m/s)t squared

0=t(7.5m/s-4.9t)

t= 1.53s

t=1.53/2

t= 0.76s to reach the maximum height

Is this correct?
