Question

Human heart is pumping blood with constant velocity vmper s at the rate of mkg per sec the force required for tgis

Answer 1

Explanation:

Force=mass per sec×velocity.

Therefore force required=m×vN.

Answer 2

Answer:

F= v dm/dt

Explanation:

From second law of Newton's

Rate of change of linear momentum is equal to the total external force on the body.We know that linear momentum P

P = m v   ( mass = m and velocity =v)

F(net)=  dP/dt

So we can say that

F(net)= m dv/dt+ v dm/dt

If velocity constant then rate of change of velocity will be zero.

dv/dt= 0

We can say that

F(net)= v dm/dt

So  F= v dm/dt
