Suppose you jump from the cliffs of Acapulco and perform aperfect swan dive. As you fall, you exert an upward force on theEarth equal in magnitude to the downward force the Earth exerts on you. Why, then, does it seem that you are the one doingall the accelerating? Since the forces are the same, why aren’tthe accelerations? Draw and Explain.
Standing on your bathroom scale in an elevator, you are shocked to see that you weigh 1.5times your normal weight! What is the acceleration of the elevator?
Consider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.47 m/s2 and the person has a mass of 98.1 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.
