Suppose that the equation of motion for a particle (where s is in meters and t in seconds) is s=(1/3)t3−8t2+64t+3 . (a) Find the velocity and acceleration as functions of t. Velocity at time t = Acceleration at time t = (b) Find the acceleration after 1 second. Acceleration after 1 second: (c) Find the acceleration at the instant when the velocity is 0. Acceleration:

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
