A snowmobile has an initial velocity of 3.0 m/s. If it accelerates at the rate of -0.60m/s2, how long will it take to stop?

Maybe c? sorry if im wrong

B) as the temperature increases, the kinetic energy of the particles increases.|-/

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.
