A box with a mass of 7 kilograms is pushed up a ramp to a height of 5 meters. what is the work done against the force of gravity? assume the ramp has negligible friction.

Answers

Answer: The work done by the ramp against the force of gravity is -343 J

Explanation:

Work is defined as the force that is causing the movement or displacement of an object.

Mathematically,

$W=F* d$

We know that:

$F=m* g$

where,

W = work done by the ramp = ?

m = mass of the box = 7 kg

g = acceleration due to gravity = $-9.8m/s^2$ (Negative sign appears because it is acting against the gravity)

d = displacement = 5 m

Putting values in above equation, we get:

$W=7kg* (-9.8m/s^2)* 5m\n\nW=-343J$

Hence, the work done by the ramp against the force of gravity is -343 J

so work done = mgh = 7×10×5 = 350 joules

so answer is 350 joules !!

really appreciate the help thanks!

Answers

If a child is born with curly hair like their mother and blue eyes like their father, it is all due to genetics. That parents DNA carries certain genes which are passed on to the child. This includes things such as hair color, eye color, hair texture and even certain illnesses.
