Question T F1 F3 F2 The above free body diagram, the forces are acting on a 3.90 kg object. The x-axis is tilted down from the horizontal by 38.4 degrees. The magnitudes of the three forces are given by: Force F1: 82.0 N Force F2: 85.0 N Force F3: 68.0 N. magnitude of the acceleration of the object? O 48.8 m/s2 O 60.3 m/s2 O 5.55 m/s2 0.0471 m/s2 Question 2 You get tired while pushing a 71.5 kg box up a 38.3" ramp, and stop half way to take a break. The box stays in place after you stop pushing. What is the force of friction on the box during your break? (The coefficients of kinetic and static friction for the box and the ramp are Uk = 0.400 and ; = 0.920, respectively.) O 506 N O 220. N O 550. N O 434 N Question 3 A rocket is attached to a person in a sled with a combined mass of 22 kg. The sled is launched with 500 N of thrust up a frictionless icy hill sloped at 16.5" from the horizontal. What is the magnitude of acceleration of the sled while it travels up the hill? O 12.9 m/s2. O 2.78 m/s2. O 25.5 m/s2. O 19.9 m/s2
