Question

Help answer this question below.

A ball is shot at an angle of 45 degrees into the air with initial velocity of 46 ft/sec. Assuming no air resistance, how high does it go?

How far away does it land?

Hint: The acceleration due to gravity is 32 ft per second squared.

Thank you!

    It is not 32.2 feet per second squared, it is per second per second. Meaning an increase of 32.2 ft per second every second until equilibrium AKA terminal velocity. The answers ahead are correct.

    d=v^2/g...or v^2sin(2@)/g but 45 degress is 90 when doubled thus 1.

    height is v^2*(sin@)^2/2g
