A roller coaster starts with a velocity of 16 m/s. One of the riders is a small girl of mass 29 kg. At points B and C, the track is circular with the radii of curvatures of 10 and 20 respectively. The heights at points A, B, and C are hA= 24.4 m, hB = 34.4 m, and hC=0 m. You may assume the track is frictionless.

a) Find the velocity of the roller coaster at point B.

b) Find the velocity of the roller coaster at point C.

c) Find her apparent weight at B

d) Find her apparent weight at C

Modern roller coasters have vertical loops like the one shown in the figure. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. A) What is the speed of the roller coaster in m/s at the top of the loop if the radius of curvature there is 11 m and the...

A sprinter is practicing her starts on a 100 m long straight track. From rest, she starts running with an acceleration of 4.2 m/s2 until she reaches her top speed of 10 m/s. Once up to speed, she immediately relaxes, decelerating slowly at a rate of -1.3 m/s2 until she comes to a stop. (a) Draw the motion diagram (including velocity vectors) for the sprinter. Please label her starting point and end point, and where she reaches her maximum speed....
