Aroller coaster, loaded with passengers, has a mass of 2 000 kg; the radius of curvature of the track at the bottom point of the dip is 24 m. if the vehicle has a speed of 18 m/s at this point, what force is exerted on the vehicle by the track? (g = 9.8 m/s^2 )a. 2.3 x10^4n b. 4.7 x 10^4n c. 3.0 x 10^4n d. 1.0 x10^4n e. none

option B

Explanation:

given,

mass of passenger = 2000 Kg

point of dip = 24 m

speed = 18 m/s

there will two forces acting on the passenger, first one is centripetal force and another one is weight.

calculation of centripetal force

    F = 27000 N

force due to weight

F = m g

F = 2000 x 9.8

F =19600 N

  force is exerted on the vehicle = 27000 + 19600

                                                      = 4.66 x 10⁴ N  = 4.7 x 10⁴ N

Hence, the correct answer is option B

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
