Answer:
The speed of the truck is 14.95 m/s.
Explanation:
Given that,
Radius = 44.2 m
Coefficient of static friction = 0.516
We need to calculate the speed of the truck
Using relation of frictional force and centripetal force
Where, r = radius
g = acceleration due to gravity
v = speed
Put the value into the formula
Hence, The speed of the truck is 14.95 m/s.
This means that the horizontal force is 750sin(25°). To be able to move the truck, force applied must be greater than static friction, which equals to its coefficient (0.77) x normal contact force (= weight)
Hence, 750sin(25°) = 0.77mg. m = 750sin(25°)/(0.77g)
Answer:
So the water does not fall because its tendency is to go straight and the force to make the curve.
Explanation:
When the water is spinning by Newton's first law the water has to follow in a straight line to divert it from this straight line a force must be applied on the water by the walls and the bottom of the bucket so that the water takes the curved path.
So the water does not fall because its tendency is to go straight and the force to make the curve.
It takes 365 1/4 days for the Earth to complete 1 full revolution.
Please mark me as brainliest. I really need it.
First, we need to find the number of protons, which is the total mass divided by the mass of one proton:
protons
Then, the total charge is the number of protons times the charge of a single proton:
