Assignment Help Physics
Reference no: EM13887602

A worker drags a box along a frictionless horizontal floor by pulling on a rope attached to the box. The position of the box is given by x(t) = (1.500 m) + (3.650 m/s)t ? (0.300 m/s 2 )t 2 + (0.089 m/s 3 )t 3 . The box has a mass of 50.00 kg.

(a) What is the position of the box at t = 2.000 seconds?

(b) What is the velocity of the box at t = 2.500 seconds?

(c) What is the acceleration of the box at t = 3.000 seconds?
