Question

Nicolo` works on weekends at a Slow Food Parlor. He fills a pitcher full of Cola, places it on the counter top and gives the 2.6 kg pitcher an 8.8 N forward push over a distance of 48 cm to send it to a customer at the end of the counter. Ignore friction. If the pitcher starts from rest, determine its final kinetic energy when Nicolo` is done pushing it.

Answer 1

Answer:4.22 J

Step-by-step explanation:

Given

mass of pitcher
`m=2.6\ kg`

Force applied
`F=8.8\ N`

distance moved
`s=48\ cm`

Applying work-Energy theorem which states that work done by all the forces is equal to the change in kinetic energy of the object

Work done by force
`W=F\cdot s`

W=
`8.8* 0.48 J`

change in kinetic Energy =
`(1)/(2)mv^2-0`

`8.8* 0.48=\Delta K.E.`

K.E.-0=
`4.22`

K.E.=
`4.22\ J`
