Let your mass be 60 kg. Determine your weight (e.g., the force of gravity on you).
Determine what normal force would be required to accelerate you upwards from ground level at a rate of 3.0 m/s2.
What would the normal force be if the acceleration described in 3) was directed downwards?
2) Two blocks (5.0 kg and 6.0 kg) are connected through a frictionless system. The angle of the ramp is 45 degrees.
Determine the acceleration of the system.
Find the tension in the string. (The 6.0 Kg is the one that's hanging while the 5.0 is on the inclined plane)
