If you throw a ball horizontally while standing on roller skates, you roll backward with a momentum that matches that of the ball. will you roll backward if you go through the motions of throwing the ball, but instead hold on to it? explain. assuming you've answered them in terms of momentum conservation, answer them also in terms of newton's third law (or vice versa, if you answered already in terms of newton's third law)

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?

Which equation is mostly likely used to determine the acceleration from a velocity vs time graph
