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.

Two train whistles, and , each have a frequency of 392 Hz. is stationary and is moving toward the right (away from ) at a speed
trasher [3.6K]

Answer:

Part a)

f = 371.1 Hz

Part b)

f = 417.7 Hz

Part c)

beat frequency = 46.6 Hz

Explanation:

Part a)

Due to doppler's Effect the frequency of the sound heard by the train which is moving away from the observer is given as

f_1 = f_0\frac{v + v_o}{v + v_s}

f_1 = 392(\frac{340 + 15}{340 + 35})

f_1 = 371.1 Hz

Part b)

Now from the second train which is approaching the person we can say

f_2 = f_0\frac{v - v_o}{v - v_s}

f_2 = 392(\frac{340 - 15}{340 - 35})

f_2 = 417.7 Hz

Part c)

As we know that beat frequency is the difference in the frequency from two sources

f_b = f_2 - f_1

f_b = 417.7 - 371.1 = 46.6 Hz

A rock is thrown straight up into the air. At the
Aleonysh [2.5K]
The answer is 3.

When a ball is thrown into the air, there is no friction (there's nothing rubbing against it), so the only force acting on the ball is gravity, which aims to pull the ball back down. Since this is the only force, the answer will equal the gravity acting on the ball. Since "weight" is defined as just that (the gravity acting on something), the answer is 3, the magnitude of the rock's weight (or the force of gravity).
