4. A soft lump of clay (m = 456 grams) is thrown at a tree with a speed of 5.9 m/sec. How lo
it take to stop the clay if the tree exerts a force of 4.0 Newtons?

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass

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 = ?

Why does gravity have a lesser than grater effect on higher altitudes?
