A cyclist having a mass of 75 kg is riding his bike on a straight road at a constant velocity of 5 ms-1 towards east. Wind is blowing against him at 6 m/s from the north-east direction at an angle of 22° as per the diagram below. What are the velocities of the headwind and the crosswind acting on the cyclist? Crosswind Wind speed: 6 m/s 22° Cyclist's velocity: 5 m/s Headwind
Question 1 (10 marks) A 75 kg cyclist is riding a 9 kg road bike on flat ground at a constant Velocity of 8 m/s. The cyclist is using a power meter, which indicates that the cyclist's power output is 216 W. a) draw the FBD & KD for the cyclist (2 marks) b) use your FBD/KD to solve for the drag force that is acting on the cyclist for the conditions above (2 mark if the cyclist now wants...
Bob starts riding his bicycle from a stopped position. When he starts pedaling, the net force on the bicycle is 37.2 N. The mass of Bob and his bike is 72.63 kg. What is his speed 12.1 s later? Give your answer in m/s. Enter your answer up to 5 decimal places. Do not enter units.
Question 6 of 8 Question 6 points Save Anawer At a given instant the top B of the ladder has an acceleration ag the instant shown. Note motion to the left has negative velocity 1 ms and a velocilty of va 8m/s both acting downward. Determine the velocity (in ms) of the bottom A of the ladder at Question 5 of 8 Question 5 points Save Anwer At a given instant the top B of the ladder has an acceleration...
1. The drive components of a two-speed bicycle are constructed as follows: • The rear wheel has a radius of 50 cm • The front gear has a radius of 10 cm, and is connected to the pedals • There are two rear gears: one with a radius of 5 cm (“high gear”), and one with a radius of 10 cm (“low gear”) • A chain connects the front gear to one of the rear gears; the cyclist can choose...
Question 1 4 points Save Answer A particle, starting from point A with an initial speed of 9.00 m/s in the drawing, is projected down the curved runway. Upon leaving the runway at point B, the particle is straight upward and reaches a height hf of 7.00 m above the floor before falling back down as shown in the diagram below. Ignoring friction and air resistance, find the initial height ho (in meters) at point A. WRITE ONLY THE NUMERIC...
Question 4 10 points Save Answer A skater is moving with an initial speed of 2.8 m/s on rough horizontal ice. He comes to rest uniformly after moving 4.6 m due to friction from the ice. What is the magnitude of friction force exerted on the skater if the mass of the skater is 72 kg? 7.9N 57N 46.7 N 61.4 N
