Problem 41P
a. What constant acceleration, in SI units, must a car have to go from zero to 60 mph in 10 s?
b. What fraction of g is this?
c. How far has the car traveled when it reaches 60 mph? Give your answer both in SI units and in feet.
ANSWER:
Step 1 of 3
A. To find the acceleration we use the formula
\(a=\frac{v}{t}\) where \(a\) is the acceleration, \(v\) is the velocity and \(t\) is the time
From the given data \(t=10 s\). Where one mile per hour is equal to \(1.60934\) kilometer per hour and one hour is equal to \(3600 s\).
\(=60 m / s \times \frac{1 \text { mile }}{1.60934 k / h} \times(3600 s / h)\)
\(=26.83 \mathrm{~m} / \mathrm{s}\)
