correction of question.
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.

Impulse=changeofmomentum
impulse=mass(vfvi)
force*time=15000
calculate force
then
force=mass*acceleration solve for acceleration
vf^2=vi^2+2ad solve for d
