Hi,

I am a "young" kid in 7th grade, so your answers should be simple. In a form like Speed = distance/time. Like an understandable and well explained form.

So how do I calculate initial speed if I have got:
acceleration : 8 m/s 2
time: 5 s
final velocity: 30 m/s

Thanks!

Distinguish among interphase, mitosis and cyrokinesis.
(what does each accomplish)

Distinguish between the structure of a duplicated chromosome before mitosis and the chromosome produced by seperation of 2 chromatids during mitosis.

I don't understand please help!!!

The "cornering performance" of an automobile is evaluated on a skid pad, where the maximum speed that a car can maintain around a circular path on a dry, flat surface is measured. Then the centripetal acceleration, also called the lateral acceleration, is calculated as a multiple of the free-fall acceleration g. The main factors affecting the performance of the car are its tire characteristics and the suspension system. A certain car can negotiate a skidpad of radius 62.2 m at 80.5 km/h. Calculate its maximum lateral acceleration.
