A mysterious rocket-propelled object of mass 42.0 kg is initially at rest in the middle of the horizontal, frictionless surface of an ice-covered lake. Then a force directed east and with magnitude F(t) = (56.0 N/s)t - (16.8 N/s2)t2 is applied. How far does the object travel in the first 3.00 s after the force is applied? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer:

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
