A bicycle and rider with mass m rolls down a hill at constant velocity under the influence of gravity with negligible rolling resistance. The hill makes an angle of θ = 19 degrees with respect to the horizontal. The force of air resistance, termed "drag", has a magnitude of Fd = 66 N. Assume that the x-direction is parallel to the slope of the hill and the y-direction is perpendicular to the hill as shown. 1. What is the sum of the forces in the y direction, ΣFy in Newtons? 2. Input an expression for the sum of the forces in the x-direction, ΣFx, in terms of the quantities given and variables available in the palette. 3.Using the information above, what is the total mass of the bike and rider m in kg?

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A fire hose held near the ground shoots water at a speed of 12.5 m/s. At what angle(s) should the nozzle point in order for the water to land 6.69 m away? What is the lowest angle in radians? What is the larger angle in radians?

A 20.4 kg mass (m) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left (T) of the mass makes an angle of 0.00° with the horizontal, and the cable to the right (T2) makes an angle (02) of 30.1°. If the mass is at rest, what is the tension in each of the cables, T and T2? The acceleration due to gravity T, T, is g = 9.81 m/s². N T1 = m N T2 =

Please answer vertically, not horizontally so that no steps are miscalculated for this problem. A unicorn is standing on a rotating platform so that it can be admired from every angle. The platform is 5 m in radius and rotates every 8 seconds (otherwise known as 1/8 of a rotation per second). What coefficient of friction must the unicorn's hooves have to keep him from slipping over the edge? This answer is not shown correctly on bartleby. Would he need a higher or lower coefficient of friction to stand closer to the center of the rotating platform? Explain.
Consider a pulley system of the type shown in the figure above. Suppose that the upper pulley has no mass and the lower two pulleys have a total mass of 9.1 kg; the block attached to the lower pulleys represents a car engine of mass 115kg . a) What is the tension T in the rope? Assume that all sloped segments of the rope are vertical. b) What force does the ceiling exert on the upper pulley, assuming you pull straight up on the rope?
