Explanation:

speed of curved path=under root of Mew and gravity

smooth surface Mew=0

so under root of 0×g

A bike travels at 7.5 m/s along a straight road, whereas a car travels at 10.0 m/s along the same road and in the same direction

Ilya [14]

Answer:

$t = 8.3 s$

Explanation:

As we know that

velocity of bike = 7.5 m/s

velocity of car is 10 m/s

deceleration of car is 0.75 m/s^2

part a)

velocity of bike with respect to car is given as

$v_r = 7.5 - 10 = -2.5 m/s$

acceleration of bike with respect to car is given as

$a_r = 0 - (-0.75) = 0.75 m/s^2$

now the distance of the bike with respect to car is given as

$d = v_i t + \frac{1}{2}at^2$

$5 = (-2.5) t + \frac{1}{2}(0.75)t^2$

$t = 8.3 s$

Part b)

What determines how the plates interact at their boundaries

swat32

Answer:

Tectonic plate interactions are of three different basic types: Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. Convergent boundaries are areas where plates move toward each other and collide.

Explanation:

Meaning the answer to your question is depending on what type of tectonic plate interaction is occurring will depend on how the plates interact.
