<h2>Acceleration of cheetah is 10 m/s²</h2>

Explanation:

We have equation of motion v = u + at

     Initial velocity, u =  0 m/s

     Final velocity, v = 50 miles/hr = 80 km/hr = 22.22 m/s    

     Time, t = 2.22 s

     Substituting

                      v = u + at  

                      22.22 = 0 + a x 2.22

                      a = 10 m/s²

     Acceleration is 10 m/s²

Acceleration of cheetah is 10 m/s²

A commercial jet liner takes off with an average acceleration of 3 g. How long does it take to reach the end of its runway which
ANEK [815]

Answer:

The time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.

Explanation:

Given;

average acceleration of the commercial Jet liner, a = 3g = 3 x 9.8 m/s² = 29.4 m/s²

distance traveled by the commercial Jet liner, s = 1542 m

The time taken for the commercial Jet liner to reach the end of its runway is calculated as follows;

s = ut + ¹/₂at²

where;

u is the initial velocity of the commercial Jet liner = 0

s = 0 + ¹/₂at²

s = ¹/₂at²

2s = at²

t = \sqrt{\frac{2s}{a} } \\\\t = \sqrt{\frac{2 \times 1524}{29.4} } \\\\t = 10.18 \ s

Therefore, the time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.

Tides occur in oceans but not in lakes why?​
lawyer [7]

Answer:

Explanation:

Tides occur mainly in oceans because that is basically one huge body of water that is free to move all over the earth. Lakes and rivers do not cover enough area to have their water be moved significantly by gravity, or in other words, to have tides.

sergey [27]

Answer:P:Increase Q:Decrease

Explanation: The price of the product will increase as the imposed per-unit excise tax on the sale of the good. This is true for both Perfectly-elastic and relatively elastic products.

The quantity demanded of the product will decrease as the price of the product increases, this his is true for both Perfectly-elastic and relatively elastic products. It will follow the law of Demand and Supply.
