Motion 1-D - Vertical

PHYS-TIKTOK ID vertical motion

Scroll down

We are using same Kinematic Equations that we discussed before, when we solve problems in this section. Just to repeat them once again, they are as follows. All the kinematic symbols stand for the same but acceleration in this case, unless stated otherwise, is gravitational acceleration.

As we know, acceleration is a vector. Therefore depending on the direction you use, the sign changes and the magnitude of the gravitational acceleration stays the same.

Tik-Tok problem 3

Part of a cheerleading routine is throwing a flyer straight up and catching her on the way down. The flyer begins this move with her center of gravity 4 feet above the ground. She is thrown with an initial vertical velocity of 30 feet per second. Take gravitational acceleration to be 32.17 ft/s^2.

a). Will the flyer's center of gravity ever reach 20 feet?
