Centripetal acceleration is given by the formula
Since we know the value of the acceleration is 9.8 m/s² and we know r, we can solve for the speed, which is the magnitude of v. Note the value of a is just the acceleration due to gravity, which is what makes the rocket orbit and not fly off into space.
Solution :
Given :
L = 1 in
d = 0.75 in
D = 1 in
Fillet radius, r = 0.063 in
We know that :
MPa
= 130 MPa
Therefore, the stress concentration factor is :
= 1.157922
Answer:
Explanation:
If a car is moving to the left with constant velocity, one can conclude that
there must be no forces applied to the car . The net force applied to the car is zero.
Since there is no acceleration ,no net force is applied , hence no force acts on the car.
Explanation:
Remember Newton's Second Law.
If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. 
So, given the same force, an object with GREATER mass will have less acceleration.
The answer is counter clockwise relative to the polaris. The polaris, also known as northern star would seem a bit more stable on the night sky as the point of vision is up north, the stars however around this would look as if it was rotating, left to right but since the earth is round in shape it follows a circular pattern.
