15+3=18km/hour
Think about it like this. The boat is going 15 faster than the river, and the river is going 3 faster than the bank, so the boat is going 18 faster than the river bank
The answer would be $3,000 because 0.30 x 10,000 = 3,000
Answer:
3.75 J
Explanation:
m = 1.5 kg
a = 0.5 m/ s^2
d = 5 m
w = F × d = (0.5×1.5) × 5 = 3.75 J
Answer:
Explanation:
The total charge is distributed over the two objects:
The plate and the rod must have . So the charge transferred from the plate to the rod is:
Number of electrons:
Apply the Pythagorean theorem to get the resultant velocity:
V =
Given values:
Vx = 57.8m/s
Vy = 5.6m/s
Plug in and solve for V:
V = 58.1m/s
EDIT: Let's get the direction of the resultant velocity as well.
This equation will give the angle of the velocity as measured off of the ground:
θ = tan⁻¹(Vy/Vx)
Again, the given values are:
Vx = 57.8m/s
Vy = 5.6m/s
Plug in the values and solve for the angle θ:
θ = tan⁻¹(5.6/57.8)
θ = 5.5°
The resultant velocity is oriented 5.5° off the ground.
