Question
session.masteringphysics.com KCH 6 HW Problem 6.52 Express your answer to three significant figures. Constants As your bus rounds a flat curve at constant speed of 19 m/s, a package with mass 0.900 kg suspended from the luggage compartment of the bus by a string 40.0 cm long, is found to hang at rest relative to the bus, with the string making an angle of 30.0 with the vertical. arad Submit Request Answer Part B What is the radius of the curve? Express your answer to the nearest meter. Submit Mo Provide FeedbackExplanation / Answer
Solution:-
The equation for the balanced force is-
T cos(theta)= mg
T=(0.9)*(9.8)/ cos(30)
= 10.18 N
b) F centripetal= T sin(theta)
mv^2/r= (10.18)sin(30)
r= (0.9*(19)^2)/ 10.8* sin(30)
= 60.17m
a) Radial acceleration
=> a= v^2/r
= (19)^2/60.17
= 5.99 m/s^2
