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? Round to 5 digits.

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. Round to 5 digits.

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! Round to 5 digits.
