Find the equation for acceleration and tension in the string when two bodies having different masses m1 and m2 connected by a string passing over a frictionless pulley: a) when two bodies moves vertically b) When one body moves vertically

Iwould sure like to answer your question but i honestly just don’t know

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.

Cis the answer  hope this : d
