Consider the launch of the space shuttle. from launch to its orbital altitude, it goes up 400 km. charlie calculates the change in gravitational potential energy in the shuttle-earth system by using the equation mgh, where m is the mass of the shuttle, g is the acceleration due to gravity at the surface of the earth, and h is the 400 km. deval, on the other hand, calculates the change in gravitational potential energy in the shuttle-earth system by using the equation -gmm/r to find the initial potential energy, where m is the mass of the earth, and r is the radius of the earth, and subtracting the initial potential energy from the final potential energy, calculated using -gmm/(r+h). who does this calculation correctly? select the single best statement about this from the statements below.

they both get it right - the two calculations give the same answer

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
