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?

Work is reduced while time is decreased

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Ibelieve the answer is arteries
