Answer: -7.86cm/s^2 don’t forget negative sign!

v1=14cm/s
dx=2.97-(-5)=7.97cm
t=2.85s

dx= v1*t+1/2at^2

I’m not writing the unit’s into the equation until the end, but you always should include them in all your calculations!! Units are very important and helpful to solve problems! Anyways, here we go;

7.97=(14*2.85)+1/2a(2.85)^2

a=[(7.97)-(14*2.85)]*2/(2.85)^2

a=(-63.86)/(8.1225)

a=-7.86cm/s^2 don’t forget the negative sign!

Any questions please feel free to ask. Thanks.

A ball initially at rest rolls down a hill with an acceleration of 3.3 m/s2. If it accelerates for 7.5 s, how far will it move?
goldfiish [28.3K]

<u>Answer:</u>

  Ball will move 92.8125 meter along the cliff in 7.5 seconds.

<u>Explanation:</u>

We have equation of motion , s= ut+\frac{1}{2} at^2, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this case initial velocity = 0 m/s, acceleration = 3.3 m/s^2, we need to calculate displacement when time = 7.5 seconds.

Substituting

  s=0*7.5+\frac{1}{2} *3.3*7.5^2\\ \\ =92.8125 meter

  So ball will move 92.8125 meter along the cliff in 7.5 seconds.
