A lazy tortoiseshell cat (4.6 kg) is sleeping soundly on a desk. It has a gravitational potential energy of 140 J even while doing absolutely nothing. What is the height of the desk?
30.4 m
14.3 m

9.7 m
3.1 m

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.
