www.webassign netweb/student/Assignment-Responses/submit?dep 15688536 A car initially traveling eastward tums north by traveling in a drolar path at unform speed as shown in the figure below. The length of the arc ABcis 226 m, and the car completes the turn in 38.0 s. (a) Determine the car's speed. m/s (b) What is the magnitude and direction of the acceleration when the car is at point B? mys? counterclockwise from the +x.axis Need Help? points i Previous Ars ers sercp 107 po33 The average distance separating Earth and the Moon (center to center)is 384000km. Use the data in the table to find the net gravitational force exerted by Earth and the Moon on a 200x1o.k spaceship located halfway between themExplanation / Answer
here,
ABC = 226 m
t = 38 s
a)
the car's speed , v = ABC /t
v = 226/38 m/s = 5.95 m/s
b)
let the radius of arc be r
2 * pi * r /4 = ABC
2 * pi * r/4 = 226
r = 143.9 m
the magnitude of car accelration , a = v^2 /r
a = 5.95^2 /143.9 m/s^2
a = 0.25 m/s^2
the direction is towards center from B ,
so , 145 degree counterclockwise from +x axis
