The acceleration of a bus is given by ax(t)=?t, where ? = 1.26m/s3 is a constant.
A) If the bus's velocity at time t1 = 1.12s is 5.09m/s , what is its velocity at time t2 = 2.13s?
B) If the bus's position at time t1 = 1.12s is 6.01m , what is its position at time t2 = 2.13s?
If a drop is to be deflected a distance = 0.28 by the time it reaches the end of the deflection plate, what magnitude of charge should be given to the drop? Imagine that the density of the ink drop is 1000 and ignore the effects of gravity.
A river has a steady speed of 0.490 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point, If the student can swim at a speed of 1.10 m/s in still water, how long does the trip take
