The direction that a weathervane mounted on top of a car points is influenced both by the wind and car’s velocity. When the car is driving due north with a speed of 50km/hr, the weathervane indicates that the wind is coming from the west. When the car doubles its speed, the weathervane now indicates that the wind is coming from the northwest. Determine the direction of the wind (when the car is idle) and its speed.

(1 pt) A plane is heading due west: its nose points towards the west direction, but its trajectory on the ground deviates from the west direction due to a sideways component of the wind. The plane is also climbing at the rate of 120 km/h (height increase per unit time). If the plane's airspeed is 550 km/h and there is a wind blowing 90 km/h to the northwest, what is the ground speed of the plane?...

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...

1. An airplane leaves airport A and travels in a straight line in a direction 30 degrees East of North at a constant speed of 300km/hr for 40 minutes, then it abruptly changes its direction to 25 degrees South of East and now travels at a constant velocity of 200km/hr for 30 minutes, and finally it abruptly heads directly South and travels at a velocity of 300km/hr for 60 minutes before landing at airport B. (a) calculate the distance, D,...

A mass of m kilograams (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixced to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The gravitational force is mg dowswards, where g- 9.8m is acceleration due to gravity, measured...
