Two experiments are conducted to determine the mass of an object. -In Experiment 1, you place the object on an electronic balance and read the object's weight.
-In Experiment 2, you apply a constant force to pull the object along a horizontal surface, while using a motion detector to measure the object's speed as it is pulled.

All frictional forces for both experiments are considered to be negligible. Which of the two experiments, if either, could be used to determine the gravitational mass of the object?

a. Experiment 2 only
b. Experiment 1 only
c. Neither experiment
d. Both experiments

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule.    set the derivative to equal -1 and solve for x.      take log base 10 of both sides. also recall that  .    so the x-coord of the point of tangency is .the y-coordinate of this point of tangency can be calculated using the original function:     using point-slope form, the equation of the tangent line is      the x-intercept of this tangent line is when the graph is at y=0.    this rounds off to  .choice c.
