Question

A 1kg ball is thrown upwards with a launch
speed of 10m/s. Assume air resistance is a
constant force of 2.5N. How much nonmechanical energy is generated from launch to
the maximum height reached by the ball

Answer 1

here you first find out the height reached by ball
acceleration due to gravity is 10 in the downward direction an addition of 2.5m/s^2 acts in the downward direction so add them both as they say air resitance is a contant force apply equation v^2-u^2=2as to find max ht
energy=work done (capability)
work done=F.s
find it!
