Answer:
4 J
Explanation:
From the image attached, we can see 2 horizontal forces acting on the box albeit in opposite directions.
Now, the net force will be;
F_net = 3 - 1
F_net = 2 N
To move a distance of 2 metres, kinetic energy is;
K.E = Force × Distance = 2 × 2 = 4 J
Answer:
A. 95N
B. ?
C.225N
D.?
Explanation:
For Mars and Pluto im not so sure about those too but for A and C I am positive those are correct.
Sorry I could not help you all the way, please dont be mad ;(
Answer:
speed
Explanation:
The slope of a line on any distance-time graph represents the speed of the object.
Velocity only comes in when there is speed of the object in a particular direction.
None of the energy is created nor destroyed
