A car on a straight flat road races a boat on a calm canal parallel to the road. The car has a constant acceleration of 1.95m/s2
Gelneren [198K]

Answer:

The winner of the race is the boat because the it get to the goal a time of t=42.42 seg

Explanation:

The problem has tow steps the first one is the time takes each vehicule to get the top speed.

1.

V_{f} =  V_{o} + a*t \\V_{o}= 0 \frac{m}{s} \\t = \frac{V_{f} }{a}  \\t_{1} = \frac{41 \frac{m}{s}  }{1.95 \frac{m}{s^{2} } }=21.02 s \\t_{2} = \frac{32 \frac{m}{s}  }{6.5 \frac{m}{s^{2} } } =4.92 s

2.

Now after they take the top speed have to know who get first to the goal

x_{f}= x_{o} + v_{o}*t + \frac{1}{2}* a *t^{2}\\  a=0 \frac{m}{s^{2} }\\ x_{o}= 0

So the speed Vo is now the final velocity calculated before

t= \frac{x_{f} }{V_{o} } \\t1= \frac{1200m }{41\frac{m}{s} } = 29.2 s\\t2= \frac{1200m }{32\frac{m}{s} } =  37.5 s\\

t1_{total}= 21.2+29.2=50.22 s\\ t2_{total}= 4.91+37.5=42.41 s

Jacob drives his car 7 km east. He stops for lunch, then drives 5 km south before driving 2 km east. What distance did he cover?
Varvara68 [4.7K]

Option (d) is correct.

Distance is the total path length covered by the object.

so, for distance, we add all the path lengths

Here the total distance =7+5+2 =14 km
