Question

Example 4 :
A raindrop of mass 2 g falling from a height of 1.00 km, hits the ground with a speed of
40.0 ms?
(a) Find the work done by the gravitational force.
(b) Find the work done by the opposing resistive force (g = 10 ms )​

Answer 1

Answer:

a)40000J

Explanation:

Velocity(g) = 10 m/s

displacement = 1km = 1000m

work = FS =

$40 \times 1000$
