A lever has a 36cm input arm and a 6cm output arm. find MA.
1 answer:
6
Explanation:
The mechanical advantage is a factor that measures how input force increases using a machine.
A lever is a simple machine with the fulcrum at the center.
To calculate the mechanical advantage M.A of levers we use the expression below;
M. A = =
= input force
= output force
a is the distance of the input force from the fulcrum
b is the distance of the output force from the fulcrum
Given
a = 36cm
b = 6cm
M.A = = 6

Answer:
The maximum speed of the car at the bottom of that drop is 26.34 m/s.
Explanation:
Given that,
The maximum vertical distance covered by the roller coaster, h = 35.4 m
We need to find the maximum speed of the car at the bottom of that drop. It is a case of conservation of energy. The energy at bottom is equal to the energy at top such that :
v = 26.34 m/s
So, the maximum speed of the car at the bottom of that drop is 26.34 m/s. Hence, this is the required solution.
Answer:
So Tammy must move with speed 4.76 m/s in opposite direction of Jackson
Explanation:
As per law of conservation of momentum we know that there is no external force on it
So here we can say that initial momentum of the system must be equal to the final momentum of the system
now we have
final they both comes to rest so here we can say that final momentum must be zero
now we have
