Question

b) A body of mass 200 g moving with the velocity of 20 metre per second experiences a
retarding force of 1000 N when it hits at target. Find the distance the body penetrates into
the target before it comes to rest.
​

Answer 1

Answer:

0.5184m

Explanation:

m= 0.2kg

u= 20m/s (72km/hr)

v= 0km/hr

F= 1000N

a= ?

s=

F= ma

5000kg/ms² = a

v²-u² = 2as

(0)² - (72)² = 2(5000)(s)

5184 = 10000s

5184/10000 = s

0.5184m = s
