F will be the answer I guess, because 5-3=2
Using s=1/2 a t ^2
25 = 1/2 x 0.5 x t^2
t = square root (25/0.25)
t = 10 seconds
Explanation:
The table is level and there are no other forces on the book, so the normal force is equal to the weight.
N = mg
N = (2.3 kg) (9.8 m/s²)
N = 22.5 N
For the purpose of the problem we can consider only the motion on the x-axis (horizontal direction).
We have two forces:the horizontal component of the force F of 3320 N acting forward, and the backward force of 550 N.
The horizontal component of the forward force is
So, the net force is
in the forward direction.
Answer:
I am not really sure but i think its option 2
