Motorcyclist (total mass 320 kg) stops from a velocity of 36km/h in 25 s without breaking.
The same motorcyclist accelerates in the same conditions from full stop to velocity of 126km/h in 6 s.
Calculate the constant forward carrying force of the engine, if the forces restricting the motion remain constant. Give the answer in 1 N precision.
The Attempt at a Solution
all i could find out is the accelerations, a1=-0.4m/s2 and a2= 0.58m/s2
and then i guess we will be interested only in a2, means only the second step of accelerating from a full stop. so F=320*0.58=185.6N
and since they asked to give the answer in 1N precision so it will be 186N.
Please tell me if i'm right
