V=D/T
V is speed
D is distance
T is time
V=D/T
31.67 m/s = 1361.81 m / T
31.67/31.67=1361.81/31.67
T=43 seconds
Hope this helps

The Mass of the car = 782.1 Kg
<h3>What is the mass of the car?</h3>
The mass of the car is calculated as follows:
- Mass = Force/ acceleration
The force on the car = 6570 N
The acceleration of the car, a = 38 - 0/4.5
acceleration = 8.44 m/s²
Mass of the car = 6570/8.44
Mass of the car = 782.1 Kg
In conclusion, the mass of the car is obtained from the acceleration and force on the car.

For a pipe open at both ends, fund frequency (Fo) given byFo = v /2L
v = velocity of sound = 340 m/s (at about 20ºC)
Fo = 340/2*5.34 = 31.8 Hz
While for the one closed at one end and open at the other end...
For a pipe open at one end, fund frequency (Fo) given byFo = v/4L
Fo = 340/4*5.34= 15.9 Hz
The answer is C. Because energy cannot be created or destroyed
