In Problems 75 through 78 you are given the equation(s) used to solve a problem. For each of these, you are to
a. Write a realistic problem for which this is the correct equation(s).
b. Finish the solution of the problem, including a pictorial representation.
75. (0.10 kg)(40 m/s) - (0.10 kg)(-30 m/s) =
76. (600 g)(4.0 m/s) = (400 g)(3.0 m/s) + (200 g)(vix)2
77. (3000 kg)vfx= (2000 kg)(5.0 m/s) + (1000 kg)(-4.0 m/s)
78. (0.10 kg + (0.20 kg)v1x= (0.10 kg)(3.0 m/s)
=

- Math Review Solve the two equations mi + MVi = mf + MVf and i Vi = (f Vf) for (a) f and (b) Vf if m = 2.00 kg, i = 4.00 m/s, M = 3.00 kg, and Vi = 0. (See Section 6.3.)arrow_forwardTwo pucks in a laboratory are placed on an air table (Fig. P11.66). Puck 2 has four times the mass of puck 1 (m2 = 4m1). Initially, puck 1s speed is three times puck 2s speed (v1i = 3v2i), puck 1s position is r1i=x1ii, and puck 2s position is r2i=y2ij. The pucks collide at the origin. a. Copy Figure P11.66 and then add vCM to your sketch. b. Does puck 2 travel a greater distance, lesser distance, or the same distance as puck 1? c. Find an expression for y2i in terms of x1i. d. If puck 1 moves 1.33 m, how far does puck 2 move before the collision?

- A ball with mass mA = 2.42 g moves eastward with speed vA = 1.73 m/s. It then collides with another ball of mass mB = 1.25 g and is moving northward with a speed vB = 2.26 m/s. After the collision, ball A now moves at 48° north of east, while ball B moves at 17° south of east. A. What are the speeds of the two balls after the collision? B. Is energy lost or gained in the system? Support your answer by calculating the change in mechanical energy of the system.arrow_forwardA force of 200N acts on a 8Kg bowling ball for 0.3 seconds. a.
