Answer #1

Force, F = mg sin(theta)

F = 89 x 9.8 x sin(13) = 196.20 N

To going uphill biker must apply twice of above force,

So,

Net force, Fn = 2 x 196.20 = 392.4 N

    3.) A jet plane is flying with a constant speed along a straight line at an angle of 30° above the horizontal. The plane has a weight W of magnitude 86500 N and its engines provide a forward thrust T of magnitude 103000 N. In addition, the lift force L (directed upwards perpendicular to the wings) and the force R of air resistance (directed opposite the motion) act on the plane. Find L and R. [L = 74900 N; R=...
