A skydiver has a mass of 61 kg. at what speed will she have a momentum of 3300 kg•m/s

1 answer:

6 0

Momentum = (mass) x (speed)

3300 kg-m/s = (61 kg) x (speed)

Speed = (3300 kg-m/s) / (61 kg)

Speed = 54.1 m/s (about 121 mph)

What is Marie's instantaneous speed at 20 minutes in miles/min?

AVprozaik [17]

Answer:

0.25miles/min

Explanation:

Instantaneous speed of a person or an object is its speed at a particular moment usually at a period of time.

The speedometer of a car reports the instantaneous speed.

It can be mathematically expressed as;

Instantaneous speed = $\frac{distance}{time}$

At 20min the distance covered is 5miles;

Instantaneous speed = $\frac{5 miles }{20mins}$ = 0.25miles/min

JulsSmile [24]

Answer:

How high the sound or how low the sound is depending on the pitch of the sound which in this case the frequencies of the sound. The higher of the frequencies , the higher of the pitch but it has the shortest length of wave (λ). That's why AM radio have a longer range but bad audio quality than FM radio that have better audio quality with shorter range.
