a mass of 0.1 kg falls freely under the action of gravity find the force acting on it it's momentum and kinetic energy after 10 sec ?

answered-by-expert Expert Answer
Force = mass × (acceleration due to gravity ) = 0.1 × 9.8 N = 0.98 N
 
---------------------------
 
Velocity v after 10 seconds is
 
begin mathsize 14px style v space equals space g space cross times space t space equals space 9.8 space asterisk times space 10 space m divided by s space equals space 98 space m divided by s end style
 
Momentum after 10 s = mass × velocity = 0.1 × 98 kg m/s = 9.8 kg m/s
 
----------------------------------------
 
Kinetic energy = (1/2) m v2 = 0.5 × 0.1 × 98 × 98  J  = 480 J
