Answer:
100cm/s
Explanation:
Given the speed of the following students;
Bernard 150 cm/s
Chloe 50 cm/s
Dev 75 cm/s
Eduardo 125cm/s
Their average speed of a student will be the mean of their individual speed as shown:
Average speed = 150+50+75+125/4
Average speed = 400/4
Average speed = 100
Hence the average speed of a student is 100cm/s
what is it? and explain pls
The velocity at which an object is sent moving and the mass of the object both play a hand in the level of kinetic energy that object produces. Mass and kinetic energy have a positive relationship, which means that as mass increases, kinetic energy increases, if all other factors are held constant.
