Explanation:

The formula for power is
empoweryourknowledgeandhappytrivia.wordpress.com
And we know that #F= ma#
where #a#- acceleration due to gravity i.e. #a= 9.8 m#/#s^2#
#d# (distance) = 5 #m#, time (#t#)= 20 #s#, mass (#m#) = 60 #kg#

Substituting these values,
#P# = #(ma * d) /t#

#P# = #(ma * 5) /20#

#P# = #(60*9.8 *5) /20#

#P= 147# #W#
