Aaron rode her bike to his house to play cards he Road for 1.6 hours at 6.5 KMH another 15 minutes at four KMH what was her aver
Kay [80]

Answer:

The average speed during the trip is 6.16 \frac{km}{hour}

Explanation:

Speed ​​is a physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed expresses the relationship between the space traveled by an object, the time used for it and its direction.

The speed can be calculated by the expression:

Speed=\frac{distance}{time}

Aaron rode his bike home for 1.6 hours at 6.5 km/h and another 15 minutes at 4 km/h. So, the distance in each of the stages can be calculated as, taking into account that 60 minutes= 1 hour:

  • distance1=speed*time= 6.5 \frac{km}{h} *1.6 hours= 10.4 km
  • distance2= speed*time= 4 \frac{km}{h} *15 minutes= 4 \frac{km}{h} *0.25 hours= 1 km

So:

  • total distance= 10.4 km + 1 km= 11.4 km
  • total time= 1.6 hours + 0.25 hours= 1.85 hours

Then:

Speed=\frac{11.4 km}{1.85 hours}

Speed=6.16\frac{km}{hour}

<u><em>The average speed during the trip is 6.16 </em></u>\frac{km}{hour}<u><em></em></u>

A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s.

Momentum = mass x velocity

Before collision
Momentum 1 = 2 kg x 20 m /s = 40 kg x m/s
Momentum 2 = 3 kg x -10m/s = -30 kg x m/s

After collision
Momentum 1 = 2 kg x -5 m/s = -10 m/s
Momentum 2 = 3 kg x V2 = 3V2

Total momentum before = total momentum after
40 + -30 = -10 + 3V2
