## What is the speed of the block at the top of the loop?

For the block at the top of the loop (point C), the velocity has a magnitude of 7.07 m/s.

### When the roller coaster is at the top of the loop the?

At the top of the loop, when you’re completely upside down, gravity is pulling you out of your seat, toward the ground, but the stronger acceleration force is pushing you into your seat, toward the sky. Since the two forces pushing you in opposite directions are nearly equal, your body feels very light.

What is the speed of the roller coaster at the top of the loop if the radius of curvature there is 15.0 m and the downward acceleration of the car is 1.50 g?

14.8 meters per second
So we’re told that at the very top of the roller coaster loop, the radius of curvature is 15 meters and the acceleration is 1.5 times g and g is 9.8 meters per second squared. So we have 14.8 meters per second must be the speed at the top of the loop.

What is the minimum speed that a roller coaster car of mass 600 kg need in MS to make it safely through a vertical loop of radius 15?

Thus, the minimum speed required to safely make it through the loop is about 12.12m/s 12.12 m / s .

## What is the speed of the roller coaster in meters per second?

The value of 30 m/s is reasonable for motion of a roller-coaster. gravitational potential energy→gravitational potential energy + heat and sound or mghA = mghB –Fd cos(1800) as seen in the equation above.

### What is the speed at the top of a roller coaster loop?

So we’re told that at the very top of the roller coaster loop, the radius of curvature is 15 meters and the acceleration is 1.5 times g and g is 9.8 meters per second squared. So we have 14.8 meters per second must be the speed at the top of the loop.

How do you measure the angular velocity of a roller coaster?

Once the car passes through the loop we are able to measure the angular velocity or the rate of change of the angular rotations, as it’s moving through that loop using the PocketLab’s Gyroscope. Roller coaster rides are notorious for creating g-forces.

Why do roller coasters have loops at the top?

Modern roller coasters have vertical loops like the one shown in Figure 6.38. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats.

## How long does it take to go through a loop?

Modern looping roller coasters all use teardrop-shaped loops to reduce the g-forces. The Flip Flap Railway was the last coaster to use a truly circular loop. The time it took the car to travel through the loop = 0.34 seconds
