A car traveling at 20 m/s "just" leaves the road at the top of a hump of the road. Determine the radius of curvature of the hump.

Describe the path of a ray that approaches a mirror parallel to the principal axis.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
