Question

A work of 4900 joule is done on a load mass 50 kg to lift it to an certain height . Calculate the height through which load is lifted?

Answer 1

hey mate !!

here is your answer !!

$\huge {Answer}$

= 10 m

$in the questions, Given:$

Mass (m) $= 50\:kg$

Acceleration due to gravity $g = 9.8\:m/s^2$

Work done (W) $= 4900\: J$

Height (h) $=?$

We know that,

$W = mgh$

So,

$4900 = 50 × 9.8 × h$

$4900 = 490h$

$h = \frac{4900}{490}$

$h = 10\:m$

Therefore,

The height through which load is lifted is $10\:m$

Answer 2

here is your answer

Given,

Work done= 4900Joules.

Mass of load = 50kg

let the height be = h

accélération due to gravity= 9.8ms^-2

Now, remember

While lifting a body of certain mass we are creating the potential energy in the body which is the work done to lift it against gravity.

Hence, potential energy = m×g×h

=> 4900= 50 × h × 9.8

=>4900/9.8×50= h

=>10m

hence the load is lifted around 10m aginast gravity.
