28. The position(x) - time () graph of a body of mass 2 kg is shown in figure. If impulse on the bodyatt2sis-10 kg m/s, then value of xo is(a) 10 m(b) 2.5 m(c) 5 m(d) 7.5 mx (m)txo

Answer»

given impulse at t = 2sec is -10 kgm/s

also impulse = mv = 2*v

so velocity is = 10/2 = 5 m/s

now x° = v*t = 5*2 = 10m

option A
