we calculate the area of rectangle and triangle formed in slope of the graph
now add them
as we know
F = ma
F = m ( v-u ) /t
(F.t ) / m = v-u
(1/2 x 10 x5 + 10 x 5 ) 10 = v-u
v-u = 75 / 10
v-u = 7.5 m/s
now add them
as we know
F = ma
F = m ( v-u ) /t
(F.t ) / m = v-u
(1/2 x 10 x5 + 10 x 5 ) 10 = v-u
v-u = 75 / 10
v-u = 7.5 m/s
