Answer-
The rider’s displacement during this time is 17.01 m
Solution-
As we know,
Where s = displacement,
u= initial velocity = 0, as the rider starts from rest
a= acceleration = 0.5 m/s²
t= time taken = 8.4 s
Putting the values,
Answer:
14.4 lb
Step-by-step explanation:
In a see-saw in equilibrium, the torque generated by one side needs to be the same generated in the other side. The torque is calculated by the product between the mass and the distance to the center of the see-saw.
The torque generated by the child is:
T1 = 60 * 3 = 180 lb*feet
So, the torque generated by the weight needs to be higher than T1 in order to lift the child.
The lowest mass is calculated when the mass is in the maximum distance, that is, 12.5 feet from the center.
So, we have that:
T2 = 180 = mass * 12.5
mass = 180/12.5 = 14.4 lb
So the lowest weight is 14.4 lb

The right answer is C. The set of all points in a plane that are a certain distance from a single point
The certain distance is called the <em>radius</em> and the single point is called the <em>center. </em>In this way, all points are a certain or, in other words, the same distance from the center. So, for the Standard Form of the Equation of a Circle we have that:
