A race-car starts at the 3 o’clock position and drives counterclockwise on a circular track with a radius 4 miles. Suppose the car travels at a constant speed of 80 miles per hour. How long does it take the race-car to complete one revolution around the track? Include units.

Imagine a CD with an outer radius of 12 mm and an inner radius of 2 mm. A speck of dust on the outer edge completes a full revolution in 0.5 seconds. A speck of glitter on the inner edge completes a full revolution in 0.2 seconds. a) What is the centripetal acceleration of the dust in m/s2? b) What is the centripetal acceleration of the glitter in m/s2?

A 5 kg mass is spun around in a circle of radius 2m with a period of 7 s. What equation would you use to calculate the centripetal acceleration? Calculate the centripetal acceleration. Possible Formulas that can be used to answer the question: v=(2πr)/T ac=v2/r ac=(4π2r)/T2 Fc=mac Fg=mg F=(Gm1m2)/d2 g=Gm/r2 T2=(4π2/Gm)r3 v=√(Gm)/r g=9.80m/s2 G=6.67x10-11 (N∙m2)/kg2

Former prince Harry's child is riding on a dangerous, old-fashioned, playground merry-go-round which completes one revolution every 8.36 seconds. The boy is standing 4.65 m from the center of the merry-go-round. What is the magnitude of the centripetal acceleration of the child? a) 3.21 m/s^2 b) 1.78 m/s^2 c) 2.63 m/s^2 d) 2.04 m/s^2 e) 3.97 m/s^2

You are on a boat in the middle of the Pacific Ocean at the equator traveling in a hydrofoil going at a constant speed of 300 ?/?. The water is perfectly still. What is your acceleration: a) If you're heading due North? b) If you're heading due East? c) If you're heading straight up (something probably went wrong at this point). Assume the following: The earth has a radius of 6371 km. The earth makes one full revolution every 24 hours. The gravitational constant at sea level is 9.81 m/s2. East and North are relative to the Earth's axial north, not magnetic north.

A car with a constant speed of 95 km/h enters a circular flat curve with a radius of 0.5 km. The friction between the road and the car's tire can supply a centripetal acceleration of 1.35 m/s². What is the acceleration the car need to remain in this curve regardless of its acceleration of 1.35 m/s²? a) 2.39 m/s² b) 1.74 m/s² c) 1.35 m/s² d) 1.39 m/s² V₁ = V + at лd²h V= C=d F = ma ac r x=x+(+v₁)t +mgh+Fyud F r
