A ball is tossed upward from a tall building, and its upward velocity V in feet per second is a function of time t, in seconds, since the ball was thrown. The formula is V(C) 80-32t if we ignore air resistance. Express using functional notation the velocity 4 seconds after the ball is thrown and then calculate that value. Is the ball rising or falling then? a. V(4)--32 ft/sec; ball is falling b. V(4) 32 ft/sec; ball is rising e V(4) 48 ft/sec; ball is rising d. v(4)-48ft/sec; ball is falling 7. Using the information from problem 6, find the velocity change from one second to the next? a. The velocity changes by -80 feet per second for each second that passes. b. The velocity changes by-32 feet per second for each second that passes. c. The velocity changes by 80 feet per second for cach second that passes. d. The velocity changes by 32 feet per second for each second that passes. 8. Section 1.1 Exercise 8a Pa
