Question

(12) A force of 100dynes act on a mass 5g for 10s the
velocity produced is.
(a) 2cm/s (b) 20cm/s (c) 200cm/s(d) 2000cm/s​

Answer 1

Answer:

F =100dyn.

m=5g

t=10s u=o. f=ma. a=f/m. a=100×10 tothe power -5 \ 5×10 to the power -3. a=0.20/s square from equation of.motion. v=u+at. v=0+0.20×10. v=2m/s. v=200cm/s aption no (c) 200cm/s
