falling from a height of 1 km. It hits the ground with a speed of 50 
. Take ‘g’ constant with a value 10 
. The work done by the (i) gravitational force and the (ii) resistive force of air is
A
(i) 1.25 
(ii) 
(ii)
B
(i) 100 
(ii) 8.75 
(ii) 8.75
C
(i) 10 
(ii) 
(ii)
D
(ii) 
Text Solution
Verified by ExpertsThe correct answer is:
C
: Here, 
km 
(i) The work done by the gravitational force
