4. Mr. Smith wants to know if he jumps off a building with a velocity of 7.00 m/s, ata 20.0-degree angle from the building, will he be able to land on the next buildings roof
that is 2.00 meters lower than the original building. These buildings are 4.00 meters
apart. If he makes it by how much? If he doesnt make it by how much does he miss it.

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.
