by factoring in gravity, i was able to get all of them except for e. and i. what is the difference between the total magnitude of impulse of the stone imparted by the hand, and the magnitude of net impulse imparted by the act of throwing?
also, i don't understand how i will be able to...
Homework Statement
Suppose you throw a stone having a mass of 0.50 kg vertically upward. Let us assume that your hand exerts an average force of 110 N over an arm displacement (upward) of 0.60 m. Through the following sequence of questions, we shall explore, in terms of the energy and...
Homework Statement
Two identical gliders are floating at rest on an air track. Glider 1 is given a quick push in the positive x-direction towards glider 2. When they hit, they stick together. The graphs below describe some of the variables associated with the motion as a function of time . The...
Homework Statement
The net force acting on a glider on an air track (an essentially frictionless system) varies with time as shown in the following diagram. The vertical scale is such that the space between consecutive vertical gridlines is 5.0 Newton(s).
The glider has a mass of...
