Hey MATE!

We are given that :

Initial velocity (u) = 15 m/s

Final velocity (v) = 0m /s

time (t) = 0.1sec

Acceleration (a) = ?

We can apply 1st equation of motion here:

v = u +at


0= 15 + a(0.1)

0 = 15 + 0.1a

- 15 = 0.1 a

a = -150 m/s ²


Mass = 150 gm => 0.15 kg

Force = > ma

= > (0.15)(-150)

Force => -225 Newton.

Hope it helps
