harina [27]

Answer:The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.

viva [34]

Answer:

the acceleration during the collision is: - 5  \frac{m}{s^2}

Explanation:

Using the formula:

a=\frac{\Delta\,v}{\Delta\,t}

we get:

a=\frac{-0.4-0.6}{0.2} \,\frac{m}{s^2} =\frac{-1}{0.2} \,\frac{m}{s^2} =-5\,\,\frac{m}{s^2}

In January 2004, NASA landed exploration vehicles on Mars. Part of the descent consisted of the following stages:
fenix001 [56]

Acceleration is given by:

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time interval

Let's apply the formula to the different parts of the problem:

A) -20.5 m/s^2

Let's convert the quantities into SI units first:

u = 19300 km/h \cdot \frac{1000 m/km}{3600 s/h} = 5361.1 m/s

v=1600 km/h  \cdot \frac{1000 m/km}{3600 s/h}  =444.4 m/s

t = 4.0 min = 240 s

So the acceleration is

a=\frac{444.4 m/s-5361.1 m/s}{240 s}=-20.5 m/s^2

B) -3.8 m/s^2

As before, let's convert the quantities into SI units first:

u = 444.4 m/s

v=321 km/h  \cdot \frac{1000 m/km}{3600 s/h}  =89.2 m/s

t = 94 s

So the acceleration is

a=\frac{89.2 m/s - 444.4 m/s}{94 s}=-3.8 m/s^2

C) -53.0 m/s^2

For this part we have to use a different formula:

v^2 - u^2 = 2ad

where we have

v = 0 is the final velocity

u = 89.2 m/s is the initial velocity

a is the acceleration

d = 75 m is the distance covered

Solving for a, we find

a=\frac{v^2-u^2}{2d}=\frac{0^2-(89.2 m/s)^2}{2(75 m)}=-53.0 m/s^2
