1. Kurdapya, a grade 12 STEM student is helping her sister solve this problem. How fast is an oxygen molecule moving if it is in a room temperature with a mass of 3.31 x 10^-26 kg and has a KE of about about 7.21 × 10^-21 kg and has a J. Let us help her calculate the answer?   2. Kurdapya successfully solved the answer so she has time to visit her mini gym. She lifts an object that weighs 350 N to a height of 3.5 m. How much work is done in lifting the object? If she wants to lift the object in just 5 s, at what rate is the work done? 3. Kurdapya then went to their playground to play tennis when she noticed that her tennis ball has a mass of 500 g. If she holds the ball above the ground at a height of 2.5 m to serve, what is its gravitational potential energy?
