Answer to Question #83612 in Mechanics | Relativity for Hghtxh

Question

An object at t = 0 moves at speed of 50 m/s. If the resultant vector exerted on the object is equal to zero, the speed of the object after moving for 10 seconds is

Answer 1

The Newton’s second law states

ma=F

If the resultant force vector exerted on the object is equal to zero, so the acceleration of the object is equal to zero too. Therefore the object’s speed remains constant.
