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...

8. A boat is heading due north as it crosses a wide river with a speed of 10.0 km/h relative to the water. The river has a current such that the water moves with a uniform speed 5.00 km/h due east. Determine the magnitude and direction of the boat's velocity with respect to an observer on the riverbank (5 points) A plane maintains a speed of 630 km/h relative to the air it is flying through, as it makes a...

The lightweight wheel on a road bike has a moment of inertia of 0.097 kg⋅ m 2 . A mechanic, checking the alignment of the wheel, gives it a quick spin; it completes 5 rotations in 2 s . To bring the wheel to rest, the mechanic gently applies the disk brakes, which squeeze pads against a metal disk connected to the wheel. The pads touch the disk 7.1 cm from the axle, and the wheel slows down and stops...

1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...

12-10. Car A starts from rest at t-0 and travels along a straight road with a constant acceleration of 3 m/s until it reaches a speed of 27 m/s. Afterwards it maintains this speed. Also, when-0, car B located 2000 m down the road is traveling towards A at a constant speed of 20 m/s. Determine the distance travelled by car A when they pass each other. 20 m/s 2000 m 12-11. A particle travels along a straight line with...

HW#5 Functions and Arrays
For HW#5 we will return to the state method of solving the
ballistic projectile problem with added twists. The goal will be to
hit a target 1000 meters east of your cannon but the wind is
blowing from the south. Your initial muzzle velocity is fixed at
110 meters per second, but you can control the elevation and
azimuth angles of your aim. Elevation angle is measured up or down.
Azimuth angle is measured right or...
