During a race, a runner runs at a speed of 6 m/s. four seconds later, she is running at a speed of 10 m/s. what is the runner's acceleration?

1 m/s². A runner that change is speed from 6 m/s to 10 m/s has an aceleration of 1 m/s².

the key to solving this problem is using the kinematics equation which means that the aceleration is related to a change of velocity in an interval of time.

We know that the runners runs at a initial velocity of 6 m/s, four seconds later, she is running at a speed of 10 m/s.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
