Answer:
One should draw a diagram showing the placement of the charges.
When both charges of -Q are placed there will be no force in the vertical direction because of cancellation of forces.
A line from one corner of the square to the other makes an angle of 45 degrees,
2 cos 45 deg will be the force due to one charge.
2 * .707 = 1.41 N
So for both charges the force is (horizontal, vertical is zero)
2 * 1.41 = 2.82 N
b) is correct
Answer:
25 m/s
Explanation:
The car's momentum is increased by the amount lost by the truck
750(15) + 7500 = 18750 kg•m/s
18750 / 750 = 25 m/s
Answer:
-223.64684 J
Explanation:
F = Force that is applied to the crate = 68 N
s = Displacement of the crate = 3.5 m
= Angle between the force and displacement vector = (180-20)
Work done is given by
The work that Paige does on the crate is -223.64684 J
Answer:
They investigated Hooke's law.
Explanation:
Answer:I think I’m not sure But I think that the force that would be accurated the car would be friction or something like that and to solve the equation you would do f/m
Explanation:
It just makes sense
