In some motorcycle races, the riders drive over small hills and the motorcycle becomes airborne for a short time interval If the motorcycle racer keeps the throttle open while leaving the hill and going into the air, the motorcycle tends to nose upward. Why?
Calculate the speed (in m/s) a spherical rain drop would achieve falling from 2.50 km in the absence of air drag and with air drag. Take the size across of the drop to be 3 mm, the density to be 1.00 ✕ 103 kg/m3, and the surface area to be πr2. (Assume the density of air is 1.21 kg/m3.) (a) in the absence of air drag = ? m/s (b) with air drag = ? m/s

Differential equations A sphere weighing 2 kg is dropped from a height of 1000 meters without initial speed. While falling you find an air resistance numerically equal to v/8 (in Newtons) where v is the speed of the sphere (in m/s).Find: a. The speed lımite of the sphere .b. The time required for the sphere to touch the ground. Pls dont skip any steps even on the integrals
You are flying a paper glider. In still air it has a speed of -100km h^-1. It is travelling on a bearing of 60 degrees and the wind is blowing at a speed of 30 km h^-1 from the North East. Express the original velocity (g) of the glider relative to the air and velocity (w) of the wind in component form, giving the values in km h^-1 to to 2 d.p.
