Answer» Answer: 20N Explanation: mass (m)=1kg Initial velocity (U) =2m/s distance covered (s)= 0.01m USING (3)rd equation of motion v2=u2=2as ∴ final velocity (V)=0 (nail does not move further) 0=(2)2+2a×(0.01) a=−200m/s2 Force of IMPACT i..e. applied by hammer F=ma =(1kg)(200m/s2) F=200N Now, using (1) st equation of motion v=u+at ∵v=0 0=2+(−200)t t=−200−2 t⇒10−2sec

Answer:

20N

Explanation:

mass (m)=1kg

Initial velocity (U) =2m/s

distance covered (s)= 0.01m

USING (3)rd equation of motion

v2=u2=2as

∴ final velocity (V)=0 (nail does not move further)

0=(2)2+2a×(0.01)

a=−200m/s2

Force of IMPACT i..e. applied by hammer

F=ma

=(1kg)(200m/s2)

F=200N

Now, using (1) st equation of motion

v=u+at

∵v=0

0=2+(−200)t

t=−200−2

t⇒10−2sec
