Explanation:

distance (km)

a) As near as I can tell from the graph, the distance travelled was 4km

b) I would answer 40 minutes, but don't be surprised if your instructor says 30 minutes.

c) The average speed is 4 km/40 minutes = 0.1 km/minute

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
