Question

If the units of force energy and velocity are 20n 200j and 5m/s find the unitsof length mass and time

Answer 1

Hyy XD

F = Ma = 20N

E = 1/2Mv² = 200j

V = 5m/sec

from 2

M = √200×2

M = 20Kg

a = 20/20

= 1m/sec²

v= u+at

t = v/a

5/1

= 5sec

v²/2a = s

25/2×1

s = 12.5 m

hope this helps.:)
