A skier leaves the ramp of a ski jump with a velocity of 30.0 m/s The slope is inclined at 50.0°, and air resistance is negligible. Find the distance (d) from the ramp to where the jumper lands and the time of flight. To find d first find delta x and delta y make them equal to ech other and solve simultaneously.
The three charged particles in the figure below are at the vertices of an isosceles triangle (where d = 1.60 cm). Taking q = 8.20 µC, calculate the electric potential at point A
A vertical solid steel post of diameter d = 24cm and length L = 2.10m is required to support a load of mass m = 8200kg. What is the strain in the post
Each tire of an automobile has an area of 0.026m^2 in contact with the ground. The weight of the automobile is 2.6x10^4 N. What is the pressure in the tires.
