A hammer having a mass of 1 kg going with a speed of 6 m/s hits a wall and comes to rest in 0.1 sec. Compute the obstacle force that makes the hammer stop.​

Answer 1

Explanation:

hope it helps you.............

Answer 2

Answer:

Mass of the hammer=1kg

Initial velocity(u)=6ms

1

Final velocity(v)=0ms

1

Tie taken(t)=0.1sec

(i)

impluse=m(v−u)=1×(0−6)

=>−6ms

1

(ii)

a retarding force that stops a hammer

i.e.,

f=

time

impluse

=

0.1

−6

=>60N

(iii)

retarding of the hammer

i.e.,

a=

m

f

=

1

60

=60ms
