A lorry of mass 1000kg moving initially at 10m/s increases to 25m/s. In 5sec the impluse on the lorry is 15,000Ns; calculate
1. Acceleration
2.The distance covered.

  • .physics -

    Impulse=changeofmomentum
    impulse=mass(vf-vi)
    force*time=15000
    calculate force

    then
    force=mass*acceleration solve for acceleration

    vf^2=vi^2+2ad solve for d
