Answer:1.04 N
Explanation:
Given
Gravitational Force on the Platter is
Tray makes an angle of
This gravitational Force has components along and Perpendicular to Platter
Perpendicular Force
Along the Tray
Thus 1.04 N is the magnitude of force that will cause Platter to slide down
Average velocity over a given time interval is the distance traveled divided by the time:
Explanation:
It is given that,
When the front wheels are over the scale, the weight recorded by the scale is 5800 N, F₁ = 5800 N
When the rear wheels are over the scale, the scale reads 6500 N, F₂ = 6500
The distance between the front and rear wheels is measured to be 3.20 m, x₂ = 3.2 m
We need to find the location of center of mass behind the front wheels. Let the center of is located at a distance of x₁. Thus balancing the torques we get :
On solving the above equation we get, x₂ = 1.69 m
So, the center of mass is located at a distance of 1.69 meters behind the front wheels.
