A small block of mass mm is given an initial speed v0v0 up a ramp inclined at angle θθ to the horizontal. It travels a distance ddd up the ramp and comes to rest.

According to the tide table below what time of day will the highest tide occur?

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
