Ariana is accelerating her car at a rate of 4.6 m/s2 for 10 seconds. Her starting velocity was 0 m/s.

What type of plate boundary interactions takes place when tectonic plates move apart?

grigory [225]

Tectonic plates 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. <span />

A rocket is fired straight upward, starting from rest with an acceleration of 25.0 m/s^2. It runs out of fuel at the end of 4.00

ANTONII [103]

Answer:

a) 200m, 100m/s

b) 710.20m

c) -117.98 m/s

d) 26.24 s

Explanation:

To solve this we have to use the formulas corresponding to a uniformly accelerated motion problem:

$V=Vo+a*t$ (1)

$X=Xo+Vo*t+\frac{1}{2}*a*t^2\\$ (2)

$V^2=Vo^2+2*a*X$ (3)

where:

Vo is initial velocity

Xo=intial position

V=final velocity

X=displacement

a)

$X=0+0*4+\frac{1}{2}*25*4^2$

the intial position is zero because is lauched from the ground and the intial velocitiy is zero because it started from rest.

$X=200m$

$V=0+25*4$

$V=100m/s$

b)

The intial velocity is 100m/s we know that because question (a) the acceleration is -9.8 $\frac{m}{s^2}$ because it is going downward.

$0=100^2+2*(-9.8)*X\\X=510.20\\totalheight=200+510.20=710.20m$

c)

In order to find the velocity when it crashes, we can use the formula (3).

the initial velocity is 0 because in that moment is starting to fall.

$V^2=0^2+2*(-9.8)*(710.20)\\V=-117.98 m/s$

the minus sign means that the object is going down.

d)

We can find the total amount of time adding the first 4 second and the time it takes to going down.

to calculate the time we can use the formula (2) setting the reference at 200m:

$-200=0+100*t+\frac{1}{2}*(-9.8)*t^2$

solving this we have: time taken= 22.24 seconds

total time is:

total=22.24+4=26.24 seconds.

Lucy and Zaki each throw a ball at a target.

alina1380 [7]

Probability of both Lucy and Zaki hitting the target = 1/4

When Zaki or Lucy throw a ball at the target there are only two outcomes for each of them ( i.e Hit or miss )

Therefore :

The probability of Lucy hitting the target = 1/2

The probability of Zak hitting the target = 1/2

<h3>Analysis </h3>

Probability of both Lucy and Zaki hitting the target

P(Lucy ) + P(Zaki ) = 1/2 + 1/2 = 1/4

Hence we can conclude that Probability of both Lucy and Zaki hitting the target = 1/4
