A car has steady speed of 8m/s .How long does the car take to travel 160m

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
