Atruck is moving around a circular curve at a uniform velocity of 13 m/s. if the centripetal force on the truck is 3,300 n and the mass of the truck is 1,600 kg, what's the radius of the curve?

a. 81.94 m
b. 348.56 m
c. 109.09 m
d. 6.30 m

The answer is  m.

Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).

It can be represented as:

where:
m - mass
v - velocity
r - radius of the curve

We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²

We need radius of the curve:
r = ?

So, if  , then:

The Correct answer to this question for Penn Foster Students is: 81.94m

i'm sorry, but can you list the answers? i cannot with something i don't know the answers to

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
