Show work! margaret, whose mass is 52 kg, experienced a net force of 1750 n at the bottom of a roller coaster loop during her school's physics field trip to six flags. what is her acceleration at the bottom of the loop?

43.46 m/

Explanation:

Two forces will be acting on her at the bottom point of the rollar coaster,

One will be mg (vertically downwards)  and other will be ma(vertrically upwards) due to the centripetal force .

So, taking the resultant of the forces , we will get

ma-mg = 1750 (Given)

m(a-g) =  1750

52(a-g) = 1750

a-9.81 = 33.65

a = 43.46

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
