Answer:
2.2386 m/s
Explanation:
I think you would use the momentum equation.
m1v1=m2v2
m1= mass of the bag (8.5kg)
v1= speed of bag (6.9 m/s)
m2= mass of bag and cart (26.2 kg)
v2= speed of cart and bag
Plug these numbers all into the equation and you solve for v2 which ends up at 2.2386 m/s
We know that the average speed is simply the ratio of the
total distance travelled over the total duration of the trip.
total distance = 500 mi + 380 mi + 600 mi
total distance = 1,480 mi
total time = 10 h + 8 h + 15 h
total time = 33 h
So the average speed is therefore:
average speed = 1,480 mi / 33 h
<span>average speed = 44.85 mi / h</span>
Answer:
2 kg
Explanation:
Acceleration = 5 m/s^2
Force = 10 N
Force = mass * acceleration
mass = force / acceleration
mass = 10 / 5
mass = 2 kg
