What is the period of a spring that oscillates with a frequency of 2.09 Hz​
Sergio [31]

Frequency, υ = 2.09 Hz

We know that time period, T = 1/υ

∴ T = 1 ÷ 2.09

⇒ T = 0.4784 seconds

What are some examples of helpful and unhelpful frictions?
ladessa [460]
Helpful friction would be the friction on something that you wanted to stop (a car) while unhelpful friction is friction on something that you want to keep going (a curling rock)

A 1700kg rhino charges at a speed of 50.0km/h. what average force is needed to bring the rhino to a stop in 0.50s?
uranmaximum [27]
From 50km/h to 0km/h in 0.5s we need next acceleration:
First we convert km/h in m/s:
50km/h = 50*1000/3600=13.8888 m/s
a = v/t = 13.88888/0.5 = 27.77777 m/s^2

Now we use Newton's law:

F=m*a

F=1700*27.7777 = 47222N

While in a park, you walk west for 52 m, then you walk 33.9° north of west for 44 m, and finally you walk due north for 25 m. Fi
vodka [1.7K]

Answer:

(a)  Total north component = (26.89 + 25) = 51.89 metres

(b) Total west component = (-34.83 + 52) = 17.17 metres.

Explanation:

Do northwest components first.

North component = (sin 33.9 x 44) =26.89  metres.

West component = (cos 33.9 x 44) = -34.83metres.

Total west component = (-34.83 + 52) = 17.17 metres.

Total north component = (26.89 + 25) = 51.89 metres
