physics - acceleration
If the length of the centrifuge arm is 12.0 m, at what speed is the rider moving when she experiences 10 g's? Express answer with the appropriate units.
Homework Answers
so v = root(a/r) = root(98/15) = 2.55 ms^-1
hope will b hlpfull
a = (v^2)/r
or
v = squareroot(a x r)
v = squareroot(98 x 12)
v = 34.29

Pumping from a Standing Position The pumped swing is modeled as a pendulum with variable length L. The rider is modeled as a point mass m, and L is the distance from the rider's center of mass to the fixed swing support point O. Conservation of angular momentum for a point mass undergoing plane motion is where H is the angular momentum of the body...

5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N.
