Kinetic energy = 1/2 M V2
At 2 m/s, the board's KE is [ (1/2) (5) (2)2 ] = 10 joules.
At 10 m/s, the board's KE is [ (1/2) (5) (10)2 ] = 250 joules.
The difference is 240 joules, which is the work you have to put into it
to give it the additional kinetic energy.

How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.
How much work must be done on a 24 kg shopping cart to increase its speed from 1 ms to 4ms?
Work done = Increase in kinetic energy SO W = (1/2) m (v22 - v12) So W = 12 x 5 x 3 = 180 J
She ran 300 meters in 30 seconds how much did her speed increase?
Her average speed was 10 m/s. You probably missed something in the question, there isn't enough there to determine "how much it increased by".
How do you teach your dog how to skateboard?
the easiest way would be to first immobilize the skateboard then, give the dog a treat for just being ontop of it, then as it becomes accustomed to that then slowly allow it to move, from there just slowly increase the speed and continue with treat eventually the dog will asume the speed with the treats
How much work must be done on a kg sled to increase its speed from 10ms to 15 ms?
To calculate the work done on the sled to increase its speed, you need to know the initial and final kinetic energy. The work done is equal to the change in kinetic energy, which is given by the formula: Work = (1/2) * m * (vf^2 - vi^2) Substitute the mass of the sled, initial speed, and final speed to find the work done.

How much it costs to get a skateboard back from a repair shop in Canada?
There's no way of telling, it'd depend entirely on their rates and what they have done. Presumably less than the value of the skateboard though.

How much work is done to increase a 20 kg scooter's speed from 10 ms to 20 ms?
The work done is equal to the change in kinetic energy, which can be calculated using the formula: W = ΔKE = 1/2 m (v_f^2 - v_i^2). Plugging in the values, the work done to increase the speed of the scooter from 10 m/s to 20 m/s is 6000 J.
