Arace car accelerates uniformly from a speed of 38.0 m/s to a speed of 61.5 m/s in 5.00s while traveling clockwise around a circular track of radius 3.80 x 102 m. when the car reaches a speed of 50.0 m/s, find the following. (a) the magnitude of the centripetal acceleration m/s2 (b) the angular speed rad/s (c) the magnitude of the tangential acceleration m/s2 (d) the magnitude of the total acceleration m/s2 exercise getting started i i'm stuck! hints: use the values from practice it to you work this exercise. suppose the race car now slows down uniformly from 61.5 m/s to 28.0 m/s in 4.20 s to avoid an accident, while still traveling a circular path 3.80 x 10 m in radius. (a) find the magnitude of the centripetal acceleration when the speed is 40.0 m/s. m/s2 (b) find the angular speed when the speed is 40.0 m/s. rad/s (c) find the magnitude of the tangential acceleration when the speed is 40.0 m/s. m/s2 (d) find the magnitude of the total acceleration when the speed is 40.0 m/s. m/s2

In this problem, you will practice applying this formula to several situations involving angular acceleration. in all of these situations, two objects of masses m1 and m2 are attached to a seesaw. the seesaw is made of a bar that has length l and is pivoted so that it is free to rotate in the vertical plane without friction. you are to find the angular acceleration of the seesaw when it is set in motion from the horizontal position. in all cases, assume that m1> m2, and that counterclockwise is considered the positive rotational direction.a) assume that the mass of the swing bar, as shown in the figure, is negligible. find the magnitude of the angular acceleration a(alpha) of the seesaw. express in variables of m1, m2, l and g.b) now consider a similar situation, except that now the swing bar itself has mass mbar . (part c figure) find the magnitude of the angular acceleration a (alpha) of the seesaw. give answer as variables as before.
