Question

10 N force acts on 2 kg body at rest. Neglecting all other forces on the body, we can say that the body
(1) has an acceleration of 5 m/s.
(2) has momentum of 30 N-s after 3 seconds of force application.
(3) has a speed of 10 m/s after 2 seconds of force application.
(4) all of above options are true.​

Answer 1

Answer:

4) all of the above options are true

explanation:➡️

F= ma

10N = 2×a

a = 5m/s^2

t= 2sec

a= 5m/s^2

u=0 (rest )

v=u+at

v=0+5×2

v=10m/s

momentum=mv+mu

=m(v+u)

v=u+at

v=0+5×3

v=15m/s

momentum= 2(15+0)

=30
