The passengers in a roller coaster car feel 50% heavier than their true weight as the car goes through a dip with a 20 m radius of curvature.

What is the car's speed at the bottom of the dip?

tyler edwards dont care

i dont get it

james delaney dont care

weight at bottom: mg+mv^2/r

but that is equal to 1.50 mg

solve for v.

Gumpy dont care

Force of gravity at the bottom=mg+mv^2/r, set that equal to 1.5(mg). All the m's divide out, leaving 1.5(g)=g+v^2/r. Plug in the numbers now.

Thog don't caree
