Answer:
the heaviest barbell that could be lifted is 390.6kg
Explanation:
Hello!
To solve this question you must follow the following steps
1. Find the amount of energy that can transform the body into motion, this is achieved by multiplying the breakfast consumed by the percentage of energy conversion.
2. We use the equation that defines the work done by a body that has weight when it is lifted, this is defined by the product of mass by gravity by height.
W=mgh
where
W=work=6898.5J
m=mass
g=gravity=9.81m/s^2
h=height=1.8m
now we solve for mass, and use the values.
the heaviest barbell that could be lifted is 390.6kg
Answer:
Explanation:
Given that nozzle discharge at constant flow rate.
Volume of tank is V
Lets constant flow rate =Q
We know that
To find the time t,at a volume V
V = Q .t
Where t is the filling time of volume .
dV/dt is the volume floe rate .
Q is the discharge.
