Me work this out.
a 3000 kg hino truck moving at a speed of 40 ms^-1 suddenly applies brakes and the vehicle slides 40m before it comes to rest. the coefficient of kinetic friction between the surface of the road and the wheels is uk=0.05.
a) calculate the kinetic friction of the force.
b)calculate the acceleration of the truck.
c) calculate the force applied by the brakes.

It's have to be 12 or idk

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
