Three identical very small 50-kg masses are held at the corners of an equilateral triangle, 0.30 m on each side. if one of the masses is released, what is its initial acceleration if the only forces acting on it are the gravitational forces due to the other two masses

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.
