Question

Susan performs a high jump where she has an initial vertical velocity of 4.04 m/s. If her center of gravity is 1.04 meters above the ground at takeoff, what is the maximum height she will be able to clear in meters (m) if her center of gravity needs to just clear the bar for the jump to be successful?

Answer 1

This is case of projectile motion.

Hrre, initial vertical velocity = = 4.04 m/s

So, her maximum height = H

As her center of gravity is already at height 1.04 m

So, she will be able to clear the height of 1.04 m + H = (1.04 + 0.833) m

Answer: 1.87 m
