A body having a mass of 20kg accelerates uniformly in a straith line according to the law, v=10 - 2t, where v is the final velocity after t in seconds.
Calculate the following:
1.1.1 The initial velocity
1.1.2 The acceleraton
1.1.3 The initial momentum
1.1.4 The kinetic energy after 4 seconds
1.1.5 The distance travelled after 3 seconds
There's more to the question but I don't know how to type in quadratics or any other sign for that matter.
Please show all steps to above mentioned questions
thanks
