slope = y2 - y1 /x2- x1
acceleration = 20/5= 4m/s
force = ma
=100×4/1000
= 0.4N
acceleration = 20/5= 4m/s
force = ma
=100×4/1000
= 0.4N

Hey but slope = v2-v1 /t2-t1 r8 so it can be 20-10/5-3 =10/2= 5 !?
no it is of total starting from 0 to 20
and for time its from 0 to 5

simply we know that vt graph constant slope means UAM .therfore
v=at [u is 0 ] a is 4m/s sqruare so F =ma and .1 kg * 4 = 0.4 N
