Question

Kim is ice-skating going 4.6 m/s. What is her velocity after 10 seconds ?

Answer 1

This is a uniform rectilinear motion (MRU) exercise.

To start solving this exercise, we obtain the following data:

Data:

• v = 4.6 m/s
• d = ¿?
• t = 10 sec

To calculate distance, speed is multiplied by time.

We apply the following formula: d = v * t.

We substitute the data in the formula: the speed is equal to 4.6 m/s, the time is equal to 10 s, which is left as follows:

`\bf{d=4.6\frac{m}{\\ot{s}}*10\\ot{s} }`

`\bf{d=46 \ m}`

Therefore, the speed at 10 seconds is 46 meters.
