3) I hate to burst your bubble, but this video is fake. There’s a battery powered skateboard hidden in the mop bucket. Assume the mass of the entire system is {43} kg, and gravity is 10 N/kg. (Maybe start with part d?) If the board can accelerate at 1.5 m/s2, how much net force is needed? If the skateboard motor can put out 300 N of force, how much friction (neglect air resistance combined) does the system have? What is the kinetic frictional coefficient for mop bucket on roadway?

Astronauts in orbit are apparently weightless. This means that a clever method of measuring the mass of astronauts is needed to monitor their mass gains or losses, and adjust their diet. One way to do this is to exert a known force on an astronaut and measure the acceleration produced. Suppose a net external force of 50.0 N is exerted, and an astronaut’s acceleration is measured to be 0.893m/s2 . (a) Calculate her mass. (b) By exerting a force on the astronaut, the vehicle in which she orbits experiences an equal and opposite force. Use this knowledge to find an equation for the acceleration of the system (astronaut and spaceship) that would be measured by a nearby observer. (c) Discuss how this would affect the measurement of the astronaut’s acceleration. Propose a method by which recoil of the vehicle is avoided.

An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1). The rope will break if the tension in it exceeds 2.55×104 NN , and our hero's mass is 87.6 kgkg1. If the angle between the rope and the horizontal is θθtheta = 11.1 ∘∘, find the tension in the rope?2. What is the smallest value the angle θθ can have if the rope is not to break?
