Viktor [21]

Answer:

$3.2048179721\times 10^{-9}\ m/s$

Explanation:

Assuming that the pacific plate moved 178 km in 1.76 million years.

s = Distance = 178 km

t = Time taken = 1.76 million years

Speed is given by

$v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{178000}{1.76\times 10^6\times 365.25\times 24\times 3600}\\\Rightarrow v=3.2048179721\times 10^{-9}\ m/s$

The speed of the plate is $3.2048179721\times 10^{-9}\ m/s$

Speed of a car is 30 m/s. Find its speed in km/h.

katovenus [111]

Answer:

108km/h

Explanation:

1km=1000m

3600s=1 hr

M/s= 3600/1000km/hr= 3.6km/hr

30m/s= 30×3.6km/hr = 108km/hr

Turning a corner at a typical large intersection in a city means driving your car through a circular arc with a radius of about

Naddik [55]

Answer:

9.89 m/s.

Explanation:

Given that,

The radius of the circular arc, r = 25 m

The acceleration of the vehicle is 0.40 times the free-fall acceleration i.e.,a = 0.4(9.8) = 3.92 m/s²

Let v is the maximum speed at which you should drive through this turn. It can be solved as follows :

$a=\dfrac{v^2}{r}\\\\v=\sqrt{ar} \\\\v=\sqrt{3.92\times 25} \\\\=9.89 m/s$

So, the maximum speed of the car should be 9.89 m/s.
