Could anyone offer any M1 help?
Q) The engine of a van of mass 400kg cuts out when it is moving along a straight horizontal road with speed 16m/s. The van comes to rest without the brakes being applied. Assume the resistive force against the van to be 200N.
a) find how long it takes the van to stop.
b) find how far the van travels before it stops.
c) comment on the suitability of the modelling assumption.
Is this suvat? I'm really confused about a) and b).
