Question

The unit of force,energy and velocity are 20N,200j and 5m/s respectivelly.find mass,length and time.

Answer 1

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.:)

Answer 2

Answer:

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 you
