The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.40 m above the floor. The ball hits the floor 0.160 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 54.7 m/s^2 82.1 m/s^2 207.9 m/s^2 109.4 m/s^2

Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of v = 2.1 cm/year. What distance, d, in meters, does the plate move in 1.8 s at this speed?
An object is moving with an initial velocity of 5.8 i m/s and a final velocity 13.8 i m/s. The time taken for acceleration is 2.2 seconds. Calculate the acceleration in m/s2 to 2 sf. In your answer, you do not enter the i unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a = -5.4 i m/s,2 you would enter -5.4
A fish swimming in a horizontal place has velocity v, = (4.0î + 1.0j)m/s at a point in the ocean where the position relative to a rock is ř, = (10.01 – 4.05)m.
