Front

When the car is at the top of the loop it just maintains contact with the track, what is the car's acceleration at this point?

Back

g downwards

Front

The car just maintains contact with the track at the top of the loop. What is its velocity at this point?

Back

√Rg

Front

A person is standing on a scale in an elevator accelerating downward. Compare the reading on the scale to the person's true weight.

Back

less than their true weight

Front

Expression for forces at the top of a Ferris Wheel in vertical circular motion?

Back

F_{c = mg + Reaction}

Front

What is the relationship when you are at the bottom of a Ferris Wheel ride?

Back

Reaction = mg + F_c

Front

Which force is zero whereby you do not feel any force coming from the seat? Options: Normal reaction force, Weight, Centripetal Force, Gravitational Force

Back

Normal reaction force

Front

A fighter aeroplane flying in the sky dives with a speed of 100 ms^-1 in a vertical circle of radius 200 m. Mass of the pilot sitting in it is 75 kg. What will be the value of force with which the pilot presses his seat when the aeroplane is at highest position (g = 10 ms^-2)?

Back
