Study the position-time graph for a bicycle.
which statement is supported by the graph?
position vs time
the bicycle has speed but not velocity
the bicycle is moving at a constant velocity
the bicycle has a displacement of 3 m.
the bicycle is not in motion.
position (m)
2 3
time (s)
save and exit

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

This is what a calorimeter is used for simpler ex, to measure calories in food.
