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 much work has to be done on a 5 kg sled to increase its speed from 10 m s to 15 m s?
Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.

Impulseforce * time = mass * velocity changeforce * time = 10So>any combination , say 5 newtons for two secondsacceleration(a) = force / mass = 5/5 = 1 (m/s)/sthen>s = v2 - u2 / 2 * as = 12 / 2s = 6 metresso >work done = force * distance = 5 * 6 = 30 joules
