Early test flights for the space shuttle used a "glider" (mass of 980 kg including pilot). After a horizontal launch at 400km/h from a height of 3300m , the glider eventually landed at a speed of 210 km/h. A) What would its landing speed have been in the absence of air resistance?

B) What was the average force of air resistance exerted on it if it came in at a constant glide of 12 degrees to the earth?

How are calculation for velocity and speed different

Atank is filled with an ideal gas at 400 k and pressure of 1.00 atm . part a the tank is heated until the pressure of the gas in the tank doubles. what is the temperature of the gas?

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
