Question

Calculate the work done in lifting a body of mass 10 kg through a height of 250 cms

Answer 1

Answer:

250m/s^2

Step-by-step explanation:

w=mgh

m=10 kg

g=10m/s

h=250 cm into m=2.5 m

mgh=10×10×2.5

Answer 2

Answer:

Step-by-step explanation:

Work done =mass* acceleration due to gravity * height=m*g*h

                                                                                Given , mass= 10kg

                                                                   Acceleration due to gravity=9.8m/s²

                                                                                  Height= 250cm=2.5m

                   =10*9.8*2.5= 245 joule
