The answer is b.
Ball rolling down a track.
So when you roll a ball down a ramp it has the most potential energy when it is at the top and this potential energy is converted to both translational and rotational kinetic energy as it rolls.
Rolling ball guide the ball and keep it on the track to reach the finish line.
Racing a cart down a ramp.
The displacement of the cart along the ramp s is 5 0 meters.
The two balls go along together for the first part of the race.
The more waves in the track the greater the fall required.
The track can be either straight or curved.
The track requires enough speed to keep the ball rolling.
Why did you create the ball from a cylinder rather than revolve a half circle or better yet use the sphere command.
To compare the kinetic energy of a ball rolling down a curved ramp and a striaght ramp.
And most of all i love the quaility and safety of this german made toy.
When it returns to its original level it slows down to its original horizontal speed but in so.
The initial velocity along the ramp v i is 0 meters second.
The ball on the dipped track gets to the end first and wins the race.
So you get the following.
This works out to v f 7 0 meters second or a little under 16 miles hour.
That doesn t sound too fast until you try to stop.
And the acceleration along the ramp is.
Wavy track this track consists or several up and down sections of track.
I know my son will get alot of play and enjoyment out of this toy for along time.
Watch this video till the end to get access to more free science expe.
As the ball on the dipped track goes down its horizontal velocity increases so it gets ahead.
I am very impressed with the ball track roll n roll n roll.
