I am currently in an online college Physical Science class. This question is one of the ones on my current homework assignment, and I have not been able to find it anywhere in the book or online. Please help!

The maximum height for a projectile is 5m. What is the y component of the initial velocity for this projectile?

A.) 98 m/s
B.) 14 m/s
C.) 10 m/s
D.) 200 m/s

Thanks!

Vy = vertical component of the initial velocity

Vy² = 2gh
Vy² = 2*9.8*5 = 98

Vy = squareroot of 98 = 9.9 m/s
answer C : 10m/s
