ME29 - Section 01 Exam 3 Practice Questions Fall 2024 12.43 The motion of a het plan just after landing on a runvay is described by the \( a-t \) graph. Determine the time \( t^{\prime} \) when the jet plan stops. Construct the \( v-t \) and \( s-t \) graphs for the motion. Here \( s=0 \), and \( v= \) \( 300 \mathrm{ft} / \mathrm{s} \) when \( t=0 \). 12.71 A particle travels along the parabolic \( y^{2}=b x^{2} \). If its component of velocity along the y axis is \( v_{y}= \) \( c t^{2} \mathrm{~m} / \mathrm{s} \), determine the \( x \) and \( y \) component of the particle's acceleration. Here b and c are constants. 12.78 A rocket is fired from rest at \( x=0 \) and travels along a parabolic trajectory described by \( y^{2}= \) \( 120\left(10^{3}\right) x \mathrm{~m} \). If the x component of acceleration is \( a_{x}=(1 / 4) t^{2} \mathrm{~m} / \mathrm{s}^{2} \), where t is in seconds. Determine the magnitude of the rocket's velocity and acceleration when \( t=10 \mathrm{~s} \). 12.100 If the motorcycle leaves ramp A traveling at \( 110 \mathrm{ft} / \mathrm{s} \), determine the height \( h \) ramp B must have so that the motorcycle lands safely. 1

Two strains of influenza have been identified that both enter the body through the mucous membranes of the nose and mouth. One strain produces only mild symptoms and is not very contagious, while the other strain incapacitates patients for 3 weeks and is highly contagious. In what way do these two strains differ?

A coffeeshop in San Francisco determines that it can sell 3000 cups of coffee at a price of $2.50, but for every $1 increase in the price, their sales will decrease by 1500 cups and for every $1 decrease, their sales will increase by 1500 cups. A function giving the revenue earned when the price of coffee is \textit{x} dollars per cup is $R(x) = $
