The average speed between 0 h and 2.340 h is 6.97 Km/h
Average speed is defined as the total distance travelled divided by the total time taken to cover the distance.
With the above formula, we can obtain the average speed between 0 h and 2.340 h as illustrated below:
- Total time = 2.340 – 0 = 2.340 h
- Total distance = 16.3 – 0 = 16.3 Km
- Average speed =?

Smaller cars have less momentum than bigger cars. What’s in motion stays in motion but objects with more momentum (can be from weight or from speed but in this case it’s about weight) tend to stay in motion longer.
Answer:
Front and the rear bumpers.
Explanation:
When two license plates are issued they need to be attached to the Front and the rear bumpers of the vehicle they were issued for.
Answer:
because theres is not enough friction so it will be super slippery
Explanation:
The general equation for the forces acting on the passengers at the topmost point of the ferris wheel is
where
mg is the weight of the passengers
R is the normal reaction of the cabin
is the centripetal force
In order to feel weightless, the normal reaction felt by the passengers should be zero. Therefore, the equation becomes:
or
where
is the angular frequency of the wheel and r is its radius. Since we know its radius,
we can calculate the angular frequency:
From which we find the frequency at which the ferris wheel should rotate:
This is the number of revolutions per second, so the number of revolutions per minute will be
