Answer: 1500 m/sec. ( b )

Solution:

V= f (λ)

Speed = frequency. Wavelength  

And frequency = 1/time period

First we will find the frequency :

Frequency = 1/time period

1/0.006 = 166.67 Hz

Using this in the equation:

Speed = frequency. Wavelength  

V= f (λ)

9 × 166.67  

= 1500.03 ≈ 1500

V (Speed) = 1500 m/s.

Note: Do not forget to mention the units or otherwise they may cost you marks!

If the car has a mass of 1,000 kilograms, what is its momentum? (v = 35 m/s).
patriot [66]

Answer:

35000 N

Explanation:

The equation for momentum is

p = m v

Where:

p = momentum

m = mass of object in kg

v = velocity of object

By simply plugging in the numbers into the equation:

1000kg x 35 m/s

You get

35000  N

soldier1979 [14.2K]
<em>Acceleration at 50m/sec² :  means every second the velocity increases by 50 m/sec. In 3 seconds the velocity increases by 150 m/s. So total will be 160 m/sec.

the formula is
</em>

<em>  V = final velocity  =  U initial velocity + acceleration a * time duration t</em>

<em>  V = 10 m/s + 50 m/sec² * 3 sec  =  160 m/sec</em>
