QP13

A spigot pours rice onto a large platform, which is the platform of a scale.

At a time t = 0.0 sec, the spigot is opened and rice begins to pour out (with initial velocity 0) at a rate of 1.00 kg/sec
onto the platform from a height of 10.0 m above.

(1 point )  (a)  At t = 10.0 sec, what is the weight of the rice on the platform?

(2 points) (b)  What does the scale read at this time? (Hint: consider the change in vertical momentum per unit time.)
