A car starts from rest with a constant acceleration. It’s velocity after travelling a certain distance is 16m/s. Find its velocity at the mid-point of the journey

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction. true or false?

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 = ?
