The Chevy Corvette Z06 is claimed to accelerate from a standing start to 60 miles per hour in 3 seconds. Estimate its accelerati

Vika [28.1K]

Answer:

The acceleration of Chevy Corvette is $8.94\ m/s^2$ .

Explanation:

Given that,

Initial speed of Chevy Corvette Z06, u = 0 (it starts from rest)

Final speed of Chevy Corvette Z06, v = 60 mph

1 mph = 0.44704 m/s

60 mph = 26.82 m/s

Time, t = 3 seconds

We need to find the acceleration of Chevy Corvette. The rate of change of velocity is called acceleration of an object. It is given by :

$a=\dfrac{v-u}{t}$

$a=\dfrac{v}{t}$

$a=\dfrac{26.82\ m/s}{3\ s}$

$a=8.94\ m/s^2$

So, the acceleration of Chevy Corvette is $8.94\ m/s^2$ . Hence, this is the required solution.

What happens to the density when water is poured into a empty glass?

san4es73 [151]

-- The density of the glass alone doesn't change.

-- The density of the water alone doesn't change.

-- The density of (the entire glass + everything IN IT) increases,
because the part that used to be air (with very low density) is
changed to water (with much higher density than the air had).
