Comet when they feel weightless?
1. Nearly zero
2. Much more than gravitational acceleration g
3. Approximately g
4. Depends on the velocity of the plane

A car rounds the top of a hill with a “kissing circle radius” R,
while maintaining a constant speed. At what speed will a
person in the car feel weightless?
“kissing circle”
- v =
√ m g r
- v =
√ m g
- v =
√ g r
- v =
g r

Tarzan is swinging across he river to meet up with Jane (for obvious
reasons) using a vine of length L that can support a maximum
tension Tmax. What is maximum speed vmax Tarzan can have at the
moment he is at an angle θ with respect to the vertical without the
vine breaking and him getting doused with cold river water?
- vmax =
TmaxL m gL^ sin^ θ
- vmax = TmaxL m
gL cos θ
vmax = TmaxL m
vmax =
TmaxL m +^ gL^ sin^ θ
- vmax = TmaxgL cos θ
