A skier traveling travelling with a magnitude of velocity v approaches a ramp that has an angle of
0. The approach to the ramp is frictionless, but there is friction on the ramp, and the coefficient
of kinetic friction between the skis and the ramp is uk. If the skier travels a distance d up the
ramp before coming to a stop, what was their initial velocity v? Your answer for v should be in
terms of d, g, uk, and 0.

A bicep muscle shown in Fig. P2.3 can apply a force F measured in Newtons (N) as a function of the elbow angle ϕ, measured in degrees as described by the quadratic equation F(ϕ) = 6ϕ − 0.04ϕ2.
For a bicep force of F = 200 N, solve the equation for ϕ by each of the following methods: factoring, completing the square, and the quadratic formula.
Using your solution from part (a), determine the elbow angle ϕ where the force exerted by the bicep is maximum. In addition, calculate the maximum force Fmax.
Plot F versus ϕ and clearly indicate the maximum force on the graph. Also clearly label the x-intercepts on the graph.

- A tourist looks up at a tall obelisk and desires to determine the height of this object. He estimates that he is 278 meters from the base of the obelisk and the angle from the horizontal is 52.1 degrees. At that moment, a bird drops a twig from the top of the obelisk. How long, in seconds, does it take for the twig to fall to the ground? Assume no initial downward velocity and no drag.arrow_forwardThe distance between the vertical axes of a water-filled U pipe is 0.80 m and is fixed to a trolley. If the car speed increases from 40 km / h to 120 km / h in 10 seconds with a constant acceleration, what will be the level difference between the branches of the U pipe.arrow_forwardA 4.20–kg block is set into motion up an inclined plane with an initial speed of vi = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of θ = 30.0° to the horizontal. An inclined plane makes an angle of θ with the horizontal. A block is shown on the plane at two different positions, a distance d apart. An arrow labeled vi is above the lower position of the block, and points up and to the right, parallel to the plane.

- A little youngster pulls a toy block up a steep hill before releasing it at the top. He believes the block will fall in his room, but his sister believes he is attempting to fire it into her room across the corridor. Mom isn't going to be pleased if she goes down the hall and steps on the block. Assume the incline's upper end is 1.00 m (horizontally) from the boy's door, and the hallway is 1.00 m wide. Who is correct? This issue, as a whole, does not fit any of the problem types you've learnt; nevertheless, it may be divided into three individual problems. The steps below will walk you through them. There is just one evaluation required.
