Ok, I have an example problem that doesn't show any of the actual calculations and I'm stumped at the process of finding the answer. The Answers were given just not the work behind it.(adsbygoogle = window.adsbygoogle || []).push({});

Bill and Ted have a skateboarding contest. They begin side by side and push their boards forward. At a speed of 5 m/s they both jump straight up and then land on their moving skateboards. Bill goes 7.5m before landing and Ted goes 6.0m before landing.

a) How long was each boy in the air?

b) How high did each boy jump?

Vi=5m/s, D1=7.5m . D2=6.0m

so.. t=D/V... t=7.5m / 5m/s = 1.5s and t=6m / 5m/s = 1.2s

so Bill has airtime of 1.5s and Ted has airtime of 1.2s.

And they give they answer of Bill is 2.76m in the air and Ted is 1.76m in the air, but unsure of the calculations for these answers..

Any help is appreciated.

Thanks
