8. A billiard ball (mass m = 0.150 kg) is attached to a light string that is 0.50 meters long and swung so that it travels in a horizontal, circular path of radius 0.40 m, as shown. 0.50 m a. On the diagram, draw a free-body diagram of the forces acting on the billiard ball. b. Calculate the force of tension in the string as the ball swings in a horizontal circle. c. Determine the magnitude of the centripetal acceleration of the ball as it travels in the horizontal circle. d. Calculate the period T (time for one revolution) of the ball's motion.

Corbin works as a bartender at the local nightclub. Due to a reduction in customers, his income has fallen sharply. As a result, he reduced his weekly purchases of frozen burritos.

Give nondeterministic finite automata accepting the set of strings of 0’s and 1’s such that there are two 0’s separated by a number of positions that is a multiple of 3. (Note: 0 is NOT an allowable multiple of 3, so 00 is not in language while 111010101111 is)). Try to take advantage of nondeterminism as much as possible.

An aquarium 2 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.) Show how to approximate the required work by a Riemann sum. (Let x be the height in meters below the top of the tank. Enter xi* as xi.) lim n ? ? n i = 1 ?x Express the work as an integral. 0 dx Evaluate the integral. J

The displacement (in feet) of a particle moving in a straight line is given by s = 1/2 t2 − 9t + 16, where t is measured in seconds.(a) Find the average velocity (in ft/s) over each time interval.(I) [4, 8](ii) [6, 8](iii) [8, 10](iv) [8, 12](b)Find the instantaneous velocity (in ft/s) when t = 8.

At winter design conditions, a house is projected to lose heat at a rate of 60,000 Btu/h. The internal heat gain from people, lights, and appliances is estimated to be 6000 Btu/h. If this house is to be heated by electric resistance heaters, determine the required rated power of these heaters in kW to maintain the house at constant temperature.
