F=-ma
F=-m×v/t
F=-100×10/0.25
F=-1000/0.25
F=-1000/25/100
F=-1000/1/4
F=-1000*4
F=-4000N is answer

gsggsh: in which class do you read ?

harshitha006: gsggsh u are under low in basics and u are commenting on us get lost

gsggsh: in which class do you read ?

gsggsh: 10

gsggsh: you are wrong

gsggsh: please show my mistake

gsggsh: if i am wrong show my mistake

Given mass, m =100g Initial velocity, u = 10m/s Final velocity, v = 0 m/s [becuz it was stopped] Time, t = 0.25 s Force = mass × acceleration [newtons 2nd law of motion] Acceleration = v-u/t = 0-10/0.25 = -40 m/s Now, F= ma = 100 × (-40) = -4000 N Thats ur answer

gsggsh: wrong

harshitha006: it's correct

harshitha006: shut up

gsggsh: please check

Maddyqueen: thanks for ur answer harshita006

harshitha006: it's ok
