What else can I help you with?
An ice skater slides in a straight line across the ice As she passes a certain point her velocity is 24 km over hr Two seconds later it is 13 km over hr What is the acceleration of the skater?
a = vf - vi = D v the answer is -11 km/hr/sec t t
A skater increases her speed uniformly from 2.0 meters per second to 7.0 meters per second over a distance of 12 meters The magnitude of her acceleration as she travels this 12 meters is?
5.0 meters every second.
How would you write and expression if an ice skater is penalized 1.2 points for a fall?
Let P be the final points, A be the awarded points, F be the number of times the skater falls. So we have P = A - 1.2*F
How many degrees will the skater turn if he skates once around regular polygon?
He will have skated a full turn of 360 degrees
How does math play a big role in ice skating?
The biggest role is in the effect of the pressure of the skates on the ice melting it to provide a film of water which lubricates the joint between the ice and the skates and lets them glide over the ice. Then there is the maths regarding the cooling system to ensure the ice stays as ice and doesn't become a big pool of water. Looking at the actual skating, there is the maths behind the movements. How a skater forces themselves forward; how the skater turns corners, how the skater jumps and does spins. For example, in doing a spin, there is conservation of momentum: when the skater spins with their arms outstretched they turn slowly, but when they pull their arms in they spin faster: with their arms outstretched, their moment of inertia is larger than when their arms are pulled in. As [rotational] momentum is speed of rotation times moment of inertia, if the moment of inertia reduces, the speed of rotation must increase to keep the same value (as the momentum is conserved) and hence they spin faster.
An inline skater traveling in a straight line goes from 3ms to 9ms in 3 s. what is the acceleration?
i dont know i asked that queston please help me!!!

Who is the world's most popular inline speed skater?
Joey Mantia
An in-line skater traveling in a straight line goes from 3ms to 9ms in 3 s. What is the acceleration?
Calculate the difference in velocity, Then divide that by the time. The result will be the acceleration, in this case, in meters per second squared.
A skater taveling in a straight line goes from 3 ms to 9 ms in 3 s What is the acceleration?
The acceleration of the skater is 2 m/s². This is calculated by taking the final velocity (9 m/s) minus the initial velocity (3 m/s), and then dividing by the time (3 s).
An ice skater glides around a rink at a constant speed of 2 ms is the skater acceleratng explain your answer?
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
Who is Brian Bowen Smith?
He is an entertainment photograher Shoot celebrities for studios. Kind of a staff photography for the studios. He was a gymnast and pro inline skater. NOT a pro skateboarder.
A inline skater is skating around a parking lot can she have constant speed changing velocity?
Yes, the inline skater can have a constant speed but changing velocity if she changes direction while skating. Velocity is a vector quantity that includes both speed and direction, so any change in direction, even if the speed remains constant, will result in a change in velocity.
Give you some examples of law of intria?
A soccer ball remains at rest until kicked due to its inertia. An ice skater continues to glide in a straight line unless acted upon by an external force. A car moving at a constant speed on a straight road will continue moving at that speed unless a force, like braking or acceleration, is applied.
How much potential energy does 60 kg skater have at 12 meters above ground?
The potential energy of the skater at 12 meters above the ground can be calculated using the formula: Potential energy = mass * acceleration due to gravity * height. Given that the mass is 60 kg, acceleration due to gravity is 9.81 m/s^2, and the height is 12 meters, the potential energy would be approximately 7,058.4 Joules.
What was the time of the fastest skater in NHL history?
Mike Gartner set the record in 1996 for skating a lap in 13.386 seconds.
Bike going 200m in 25 seconds and a skater going 400m in 40 seconds who is traveling faster and how fast is that person going?
The skater is going faster.The skater is traveling at 10 m/s (36 kph or 22.369 mph)compared with the cyclist that is traveling at 8 m/s (28.8 kph or 17.895 mph)200/25 = 8 m/s400/40 = 10 m/s
