Best ResponseYou've already chosen the best response.2Work = force × distance. Plug in your t=2s to solve for s, then multiply.

Best ResponseYou've already chosen the best response.2yes. s is 1 meter force is 6 N work is 6 Nm

Best ResponseYou've already chosen the best response.2the question says "6 kg under a force that causes a displacement..." we need to find F, using F= ma we need a use d = 1/2 a t^2 we know d and t so we find a, then F and finally W = F d

Best ResponseYou've already chosen the best response.2d (or s) in this case is 1 m t is 2 sec 1 = 1/2 a 2^2 a= 1/2 m/s^2 F= ma = 6*1/2 = 3 N W = F d = 3N * 1m = 3 Nm = 3 J

Best ResponseYou've already chosen the best response.2your question says: mass 6 kg is under a force of 6 N ... you gave the force as 6 N so that is what I would use....

Best ResponseYou've already chosen the best response.2Q14 requires that you find the force... Your 1st question may be inconsistent? i.e. 6 kg and 6 N don't mesh with the displacement?
