Question

One end of a cord is fixed and a small 0.400-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m, as shown in the figure below. When

θ = 23.0°,

the speed of the object is 5.50 m/s.

An object is swinging to the right and upward from the end of a cord attached to a horizontal surface. The cord makes an angle θ with the vertical. An arrow labeled vector **v** points in the direction of motion.

(a) At this instant, find the magnitude of the tension in the string.

Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. N

(b) At this instant, find the tangential and radial components of acceleration.

(c) At this instant, find the total acceleration.

inward and below the cord at

Your response differs from the correct answer by more than 10%. Double check your calculations.°

(d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up?

(e) Explain your answer to part (d).

Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. N
