Answer:

Yes

Explanation:

The velocity vector is used to determine the velocity in a given time interval. It is calculated by dividing the displacement by the elapsed time, according to the following formula: We must remember that velocity is a vector. Therefore, it has magnitude and direction. Answer: Velocity is the displacement of an object during a specific unit of time.

Answer:

Explanation:

2) From F=ma

Force =15×40=600N or kgm/s2

3)From the same equation making acceleration the subject of the formula will give

a=f÷m

=24÷4=6m/s2

4)m=f÷a

=45÷15=3kg

An observer sitting on shore sees a canoe traveling 5.0 m/s east, and a sailboat traveling 15.0 m/s west. What is the velocity o

Dovator [93]

Answer:

Vs/c = 20 [m/s]

Explanation:

This is a problem of relative velocities, as velocity is a vector we can use addition or subtraction of vectors for the solution.

We are asked for the velocity of the sailboat with respect to an observer located in the canoe.

$V_{s/c}=V_{sailboat}-V_{canoe}\\V_{s/c}=15-(-5)\\V_{s/c}=20[m/s]$

Why is the speed of the canoe negative?, it is negative because the canoe moves in the opposite direction to the sailboat.
