A boat with a mass of 1000 kg drifts with the current down a straight section of river parallel to the +x axis with a speed of 2.0 m/s. At t 0 the boat engages its engines, and accelerates at 2.7 m/s7. If the boat is oriented with its nose 45 from the +x axis, which of the following is a possible value for the boat's momentum at t- 3.0 s after the engine had started?

8100 kgm/s is a possible value for the boat's momentum at t- 3.0 s after the engine had started

m=1000kg

a=2.7 m/s^2

t=3

I=F/t

I=2700/2

I=900

F×t=P

P = momentum

t=time

f= force

F×t=P

P=2700×3

P=8100 kgm/s

Momentum is the result of a particle's mass and velocity combined. A vector quantity with both magnitude and direction is momentum. A particle's force is equal to its rate of change in momentum over time, which is stated in Isaac Newton's second equation of motion.

Any grouping of particles has a momentum equal to the vector sum of its momenta. The third law of Newton asserts that forces between particles are equal and opposite, and that any change in one particle's momentum is totally counterbalanced by a similar change in another particle's momentum.
