Two forces, F1 = (6.10î + 4.30ĵ) N and F2 = (3.40î + 7.65ĵ) N, act on a particle of mass 2.20 kg that is initially at rest at coordinates (+2.05 m, −4.50 m).
(c) What displacement does the particle undergo during the first 10.7 s?
(answer in m)
A space probe of mass 5.00 x 104 kg is traveling at 1.10 x 104 m/s through deep space. No forces act on the probe except that generated by its own engine. No forces act on the probe except that generated by its own engine. The engine exerts a constant external force of 4.00 x 105 N, directed parallel to the displacement, which is 2.50 x 106 m. Determine the final velocity of the probe.
A particle of mass 5.70 kg moves in the horizontal xy plane. The only force acting on the particle with component in the xy plane has expression (in newtons) F =4.70x2ı^, where x is in meters. Assume that the particle's trajectory is a straight line from the position (in meters) r0=2.10ı^ +2.10ȷ^ to the position (in meters) rf=6.50ı^ +2.10ȷ^. Also consider that its speed at position r0 has a magnitude of 3.80 m/s.
Calculate the magnitude (in m/s) of the particle's velocity at position rf. Give your answer to three significant figures. (only numbers)
