Answer:
1.23 m/s
Explanation:
p=mv
57.2 = 46.5v
v= 57.2/46.5
v= 1.23
If you want to verify your answer, just insert the value of v in the equation.
Constant velocities is an objects velocity is not changing.This means it is moving at the same speed.
Constant acceleration means that it is increasing by the same value.so the speed increases by the same amount every second
Constant position means it is not moving so it does not have any velocity at all so 0 velocity.
I looked it up and it gave me educational exercise, but I don't know if it is right.
12 is correct
Explanation: it's a cube
For a lever, the mechanical advantage is the ratio of the lever arms. Since the lever arm of the opener is always greater than that of the output arm, the mechanical advantage is greater than 1.
