Hi! Please help answer and understand these problems... THANK YOU!

 

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 7.21 x 10-21 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? 4. It's 5:00 PM and Kurdapya needs to finish her physics module, one of the problems states that a rocket and a spacecraft were attached and has a combined mass of 3.8 x 105 kg and is to reach a speed of 12.3 km/s, she needs to know how much kinetic energy will it have. 5. The next day, Kurdapya craved for some riped guava fruit. She has to climb the guava tree however she realized that she is already 65 kg and the tree is 7.2 meters high. Let us calculate the power required for her to climb the tree in 15 seconds.
