here's the problem...

Jane, looking for Tarzan, is running at top speed (5.6m/s)and grabs a vine hanging vertically from a tall tree in the jungle. How high can she swing upward?

Answer 1

Jane's initial velocity is 5.6 m/s. The equation for the height of a swing is:

h = (v^2/2g)sin2θ

where v is the initial velocity, g is the acceleration due to gravity (9.8 m/s^2), and θ is the angle of the swing.

Assuming θ is 90 degrees, the equation becomes:

h = (5.6^2/2*9.8)sin2(90)

h = 28.8 m
