Question

Question 14 is the question

Answer 1

Answer:

Force =50N

Distance = 2.25m

Explanation:

Given:-

Mass =10g = 10^-2 kg

u = 150m/s

v=0m/s

t=0.03s

To find =

S and Force Applied

Solution:

a=v-u/t

a=0-150/0.03

a=-5 × 10³ m/s

a= - 5000

s=ut+1/2at²

s=(150)(3/100)+1/2(-5000)(3/100)²

s=4.5+1/2×(-5000)×3/100×3/100

s=4.5 -2.25

s=2.25m

...................

Force = ma

= 1/100 × (-5000)

= -50N

F= 50 N

" - " represents that the force exertedexerted by the wooden block is in opposite direction

to the force applied by the bullet.

Hope it helps.
