While in an elevator, you decide to take some weight readings of yourself to determine the elevator’s acceleration. When the elevator is stopped, you read a weight of 58.8 kg. When the elevator is moving, you measure a maximum weight of 62.4 kg, and a minimum weight of 57.9 kg. (a) What is the maximum upward acceleration of the elevator? (b) What is the maximum downward acceleration of the elevator?

Assume that while ascending, an elevator has the same magnitude of acceleration "a" during starting (accelerating) and stopping (decelerating). A person stands on a scale in that elevator, and hence pushes downwards on the scale. The scale also reacts with an upward normal force. The maximum and minimum scale readings are Nace = 600 N and N dec = 400 N, respectively. acceleration of...

How much difference is there between your apparent weight when standing on flat ground at the equator v.s. at the south pole v.s. at 60 degree latitude? Assume Earth's radius is 6,380 km. What period of rotation for Earth would make you feel weightless at the equator?

E. Suppose you are standing on the scale in the elevator and the
elevator is accelerating downward with
an acceleration smaller than 9.8 m/s2
i. Draw free-body diagrams of yourself, the scale, and the floor
of the elevator where it interacts
with the scale.
ii. How must the magnitude of the force exerted by the scale on
you compare with your own
weight?
iii. How must the reading on the scale compare with the reading
you make when the elevator...

If you weigh 660 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 16.0 km ? Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be G = 6.67×10−11 N⋅m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 . Express your weight wstar in...

You are in your favorite elevator, coming to a stop as you go from the ground floor to the 4th floor. a) What forces are acting on you as you are coming to a stop in the elevator? Normal force upward and Force of gravity upward Normal force downward and Force of gravity upward Normal force downward and Force of gravity downward Normal force upward and Force of gravity downward Just the Force of gravity downward b) As you are...

When you walk and your heel strikes the ground, there is a total
force from the ground (a vector sum of the friction force and the
normal force) that is directed along your leg. For a regular gait,
the leg is at a 25° angle, and the normal force peaks at 1.1 times
the body weight. Assume the person has a mass of 50 kg.
A) For a normal gait, compute the magnitude of the normal force,
the magnitude of...

Variation in your apparent weight is desirable when you ride a roller coaster; it makes the ride fun. However, too much variation over a short period of time can be painful. For this reason, the loops of real roller coasters are not simply circles like (Figure 1) . A typical loop is shown in(Figure 2) . The radius of the circle that matches the track at the top of the loop is much smaller than that of a matching circle...
