A rollercoaster is designed with a 10 m tall vertical circular loop. Calculate the minimum speed necessary to get around the loop without falling down.
Added by Anonymous 0.
Step 1
First, we need to find the minimum speed at the top of the loop to keep the passengers from falling. At this point, the gravitational force (mg) and the centripetal force (mv^2/r) must be equal to keep the passengers in circular motion: mg = mv^2/r Show more…

A roller coaster needs to complete a vertical loop that has a radius of 14.4 meters. What must the coaster's minimum speed be at the top of the loop? (A) 5 $\mathrm{m} / \mathrm{s}$ (B) 7 $\mathrm{m} / \mathrm{s}$ (C) 10 $\mathrm{m} / \mathrm{s}$ (D) 12 $\mathrm{m} / \mathrm{s}$ (E) 14 $\mathrm{m} / \mathrm{s}$
A roller coaster includes a vertical circular loop of radius 20.0 m (Fig. 5.19a). What is the minimum speed at which the car must move at the top of the loop so that it doesn’t lose contact with the track
