A car, initially traveling 28.0ft/s, steadily speeds up to 50.0ft/s in 7.40s. Determine all unknowns and answer the following qu
nataly862011 [7]

Explanation:

Given:

v_0 = 28.0\:\text{ft/s}

v = 50.0\:\text{ft/s}

t = 7.40\:\text{s}

First, we calculate the acceleration of the car during this time:

v = v_0 + at \Rightarrow a = \dfrac{v - v_0}{t}

Plugging in the given values, we get

a = \dfrac{50.0\:\text{ft/s} - 28.0\:\text{ft/s}}{7.40\:\text{s}} = 2.97\:\text{ft/s}^2

Now that we have the value for the acceleration, we can solve for the distance traveled during the time t:

x = v_0t + \frac{1}{2}at^2

\:\:\:\:=(28.0\:\text{ft/s})(7.40\:\text{s})

\:\:\:\:\:\:\:\:\:\:\:\:+ \frac{1}{2}(2.97\:\text{ft/s}^2)(7.40\:\text{s})^2

\:\:\:\:= 289\:\text{ft}

Pavlova-9 [17]

Answer:

No.

Explanation:

No, all the pieces of paper did not remains waterproof because expansion of paper occur due to high temperature of hot water. We know that materials expand when they experience high temperature and contract when they observe cold temperature. So the pieces of paper remains waterproof which were put in cold water while those were not waterproof which were put in hot water.
