Question

Force is applied on an object of mass 2 kg at rest
on a frictionless horizontal surface as shown in the
graph. The speed of object at
t = 1 s will be:--
(1) 7.5 m/s
(2) 12.5 m/s
(3) 10 m/s
(4) 25 m/s
​

Answer 1

Answer:

I think its third option if it is correct then infor me please

Answer 2

Answer:

option 1 is correct

Explanation:

on this graph while taking the area we get impulse

F x t = m(v-u)

15= 2(v)

v= 15/2 = 7.5m/s
