1. The head of a rattlesnake can accelerate 50.0 m/s in striking a victim. If a car could do

Maslowich

Answer: 0.492 s

Explanation:

We can use the following equation to solve this problem:

$V=V_{o}+a.t$

Where:

$V=24.6 m/s$ is the car’s final velocity

$V_{o}=0 m/s$ is the car’s initial velocity (it starts from rest)

$a=50 m/s^{2}$ is the car's acceleration

$t$ is the time we have to find

Isolating $t$ :

$t=\frac{V-V_{o}}{a}$

$t=\frac{24.6 m/s-0 m/s}{50 m/s^{2}}$

Finally:

$t=0.492 s$

Please Help!!

Allushta [10]

Answer:

h = 219.96 m

Explanation:

Speed of the stone with which it was thrown horizontally, v = 10 m/s

We need to find the height of the cliff if the stone’s trajectory time from the top of the hill to the bottom to be 6.7s.

It means we need to find the distance covered by the stone. As the horizontal speed of the stone is given , it means there is no vertical motion in the stone,u'=0

Using second equation of motion,

$d=u't+\dfrac{1}{2}at^2$

Put u'=0 and a=g

So,

$d=\dfrac{1}{2}gt^2\\\\\text{Putting all the values to find d}\\\\d=\dfrac{1}{2}\times 9.8\times 6.7^2\\\\d=219.96\ m$

So, the height of the cliff is 219.96 m.

A person can run 400m in 72 s.. At what speed are they running

rewona [7]

Speed = distance/time
= 400/72
=5.55 m/s
