Question

The height of a projectile that has been launched upward can be determined by finding the sum of the product of one-half of the object’s acceleration and t2, the product of the object’s initial velocity and t, and the object’s initial height, where t represents the number of seconds after the object has been launched. An object’s acceleration can be assumed to be -32 ft/s2, which is the acceleration due to gravity.
c. If a projectile is launched into the air from the ground with an initial velocity of 192 feet per second, how long after launch will the projectile be at a height of 320 feet? S

Answer 1

I love physics

Answer 2

Is this kinematics?

Answer 3

Use one of the formulas from your formula sheet and plug the values in.

Answer 4

I think it's the one with h(final)=1/2a*t^2+vt+h(initial)

Answer 5

Do you understand the formula?

Answer 6

yes thank you
