NASA sends Lauren to an unknown planet (this is WY in the future). When she drops (think about the initial velocity if you drop something) a hammer on this planet, she discovers it takes 0.74 s to fall 3 m to the ground. What is the acceleration due to gravity on this unknown planet?

You can decrease the resistance of a length of wire by

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.

Agroup of monkeys is trying to cross the river in a rowboat. the maximum buoyant force on the rowboat is 2,000 n. the weight of the rowboat is 1,000 n. each monkey has a weight of 150 n. how many monkeys can safely cross in the rowboat at one time? explain your reasoning, including any calculations you used to find the answer.
