A diagram represents a 5 N force to the North and a 12 N force East acting on an object P of mass 6.5kg.

Question

-The Magnitude of the Net Force is 13 N
- The direction it accelerates is 23 degrees North of East.

FIND:
(A) If the object has an intial speed of 8 m/s in the direction opposite of the net force. How long does it take for the object to come to a stop?

________

Answer 1

F=ma
a=F/m = 13/6.5 =2 m/s²
v=v₀-at
v=0
v₀-at=0 =>t=v₀/a=8/2 = 4 s
