14-48 The man having a weight of 150 lb is able to run up a 15-ft-high flight of stairs in 4 s. Determine the power generated. How long would a 100-W light bulb have to burn to expend the same amount of energy?

An object with a mass of 0.45 kg is released from rest while immersed within a fluid. It reaches a speed of 50.6 percent its maximum speed in a time of 0.5 seconds. What is the object's terminal speed if the resistive force acting is given by; R = -bv ? (Assume that the gravitational force also acts)

F = (C · t²) Q14. As shown in the image below, the force acting on the box is N, where constant C = 10 and t is time in s. Determine the magnitude of the total impulse (in N.s) done by force F to the box during the period from t = 0 to t = 1.5 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F Your Answer: Answer 3 5 4

Q14. As shown in the image below, the force acting on the box is F = (C · t²) N, where constant C = 3 and tis time in s. Determine the magnitude of the total impulse (in N-s) done by force Fto the box during the period from t= 0 to t= 1.4 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F 4 Your Answer: Answer
