6 0

Answer:

Difference between tangential and angular acceleration are mentioned in points.

Explanation:

We have to find the difference between tangential and angular acceleration:

Tangential acceleration (a_t) :

  • Its function is to change the magnitude of velocity.
  • Defined as rate of change of linear speed.
  • Formula a_t=\frac{dV}{dt} =R\alpha

Angular acceleration (\alpha) :

  • Its the rate of change of angular acceleration.
  • Its value is same for different location of the same body.
  • It is also the ratio of tangential acceleration and Radius.
  • Formula \alpha = \frac{d(\omega)}{dt}  and \alpha =\frac{a_t}{R}

How does eating food produced locally benefit the environment?
fomenos

Answer:

Eating food produce locally makes it where big trucks don't have to bring it to the restaurant  

Explanation:

When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.

A runner starts from rest and stops in 12 seconds. He covers
Schach [20]

Answer:

b 1.39 m/s²

Explanation:

Given the following data;

Time = 12 seconds

Distance, S = 100 m

Since it's starting from rest, the initial velocity is equal to 0m/s.

To find the acceleration, we would use the second equation of motion;

S = ut + \frac {1}{2}at^{2}

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

100 = 0(12) + ½*a*12²

100 = 0 + 72

100 = 72a

Acceleration, a = 100/72

Acceleration, a = 1.389 ≈ 1.39 m/s²
