100 degrees C equals how many degrees F?​

Why does the input force have to be greater than the force needed to lift the bale?

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
