Question

a) A certain particle has a weight of 39 N at a point where g = 9.80 m/s^2. What are its (a) weight and (b) mass at a point where g = 7.2 m/s^2? What are its (c) weight and (d) mass if it is moved to a point in space where g = 0? b) The velocity of a 5 kg particle is given by V=(6ti+2t^2j) m/s, with time t in seconds. At the instant the net force on the particle has a magnitude of 45 N, what are the direction (relative to the positive direction of the x axis) of (a) the net force and (b) the particle's direction of travel?

Explanation / Answer

A)weight=mg; weight at g = 7.2 m/s^2 is=28.65 N; mass=3.98 kg; at g = 0; weight =0 kgs; mas=3.98 kg; B)at t=1.6771 sec; the weight of 5 kg particle is equal to 45N a)48.2 degrees; b)29.2 degrees;
