Question

AN OBJECT OF 125KG IS ACCELERATED UNIFORMLY FROM A VELOCITY OF 5M/S TO 8M/S IN 6SECOND .CALCULATE THE INITIAL AND FINAL MOMENTUM OF THE OBJECT.ALSO FIND THE MAGNITUDE OF FORCE ASSERTED ON THE OBJECT???​

Answer 1

Step-by-step explanation:

Mass of object, m=100kg; initial velocity, u=5ms

−1

; final velocity, v=8ms

−1

; time, t=6s

Initial momentum =mu=100×5=500Ns

Final momentum =mv=100×8=800Ns

Force exerted on the object

F=

t

mv−mu

=

6

800−500

=

6

300

=50N
