The answer is C: West to the East
Answer:2538.43 N
Explanation:
Given
Mass of Log=205 kg
Ramp angle
Coefficient of Friction=0.855
log acceleration
Let T be the Tension
Here
T=849.04+132.63+1556.76=2538.435 N
Answer:
System with earth at centre and body revolving around it.
Explanation:
Given that gravitational and kinetic energy should be nearly equal without changing the mass or height.
So ,
Let us consider a system where we have a body revolving around the earth with a velocity such that it remains in orbit.
Gravitational potential energy at a height h from the ground is given by
For velocities satisfying abow the system can have gpe and ke same in ideal cases.
[Note: For the abow velocity usually the body will escape as potential at infinity will be zero .This can just be a type of system where gpe and ke will be equal without mass and height changing.]
