a) What force is needed to give amass of 20kg an acceleration of 30m/s2?
b) Find the accelerating force when a car having a mass of 1.7Mg enhances its speed with a constant acceleration of 3m/s2
c) A force of 40N accelerates a mass at 5m/s2.Verify the mass. [8kg]
d) Determine the force acting downwards on a mass of 1500g suspended on a string. [14.72N]
e) A force of 4Nmoves an object 200cmin the direction of the force. What amount of work is done?
can u eplain me it detailed ?
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
