Please make it clear which questions I am not to grade if you do more than 13 A force =2 Î - 3 Ĵ + 10 &Kcirc; N acts on a small object of mass 100g. It the displacement of the object is = 6Î - 3Ĵ m. find the work done by the force. What is the angle between and ? A horizontal spring has spring constant k = 250 N/m. How much work is required to compress it from its uncompressed length (x = 0) to x = 12 cm?

Explanation / Answer

Q2. WORK REQUIRED -

W = 1/2(250 N/m)(0.12m)^2

= 1.8 J
