math questions
Hello, my friend!! how are you, I need those questions to be solved. like last time, please, just provide an explained answer for each question.

1- Shanghai Tower (2073 ft) is one of the tallest buildings in the world. Assuming that Superman weights 92 kg, how fast (in ft/s) does Superman need to be moving to leap it?
2-How much force (in lbs force) would Superman exert to make the leap above? Assume Superman accelerates in 1/4 second. You’ll need to convert your answer from kg ft/s2 to kg m/s2 (a N). There are 3.3 ft in 1 meter. There are also 4.4 N in a lb force.
3-How fast (in m/s) does Superman need to be moving to leap the Shanghai Tower on Mars? Mars has a gravity of 3.7 m/s2. Be sure to watch your units!
4-I’m doing some tests on adamantium (the mysterious metal that laces Wolverine’s bones). I’ve discovered that it took 720 J to raise 10 g of adamantium from 25 °C to 35°. What is the specific heat of adamantium?
5-Iron starts to melt at 2800 °F. The Iron Man suit is pure iron and weighs 225 pounds. If the suit starts at room temp (20°C), how many Joules of heat could the suit handle from the Melter’s “Meltaray”? (siron = 0.450 J/g °C; 1 lb = 2200 g)
