Answer:

v = u + at \\ v = 2 + ( - 5)( \frac{1}{2} ) \\ v = 2  + \frac{( - 5)}{2}  \\ v =  \frac{4 + ( - 5)}{2}  \\ v =  \frac{ (- 1)}{2}  \\ v =  - 0.5 \: m {s}^{ - 1}

<h3><em><u>-0.5 m/s</u></em> is the right answer.</h3>

The cheetah is the fastest land animal, capiable of attaining a speed of 110 km/h. In August 2009 , the world record for the men
lozanna [386]

Answer:

About 3 times faster

Step-by-step explanation:

Cheetah's speed = 110 km / hr

World 100m sprint record :

Speed of sprinter :

Distance / time

100 m / 9.58s

= 10.438413 m/s

Convert Cheetah's speed to m/s

110 km/hr = (110 * 1000)m / (60 * 60 s)

= 110000 m / 3600 s

= 30.55555 m/s

Number of times cheetah is faster than sprinter :

30.55555 m/s ÷ 10.438413 m/s

= 2.927 times

PLS HELP the LAST QUESTION, please...
Alex73 [517]

Answer:

280 Cubic inches

Step-by-step explanation:

When finding the volume, the equation is V=l*w*h

Therefore, the equation should be:

10.1*3.9*6.8

This is equal to exactly 267.852

However, the answer is 280 cubic in. because it's a larger number and it's about 13 from the actual answer. On the other hand, 250 cubic in. is about 17 from the actual number.
