A box slides down a rough plane inclined at an angle of 20° to the horizontal. The coefficient of sliding friction between the box and the plane is μ = 0.33. Calculate the magnitude of the acceleration of the box, in ms-2, to two significant figures. (Take the magnitude of the acceleration due to gravity, g, to be 9.8 ms 2.)

An object is projected upward from ground level at an angle (Theta) and the air resistance is negligible. If the initial velocity, v0, of the object is given in ft/sec and time t is measured in seconds, then the formulas for the object's height h and the horizontal distance traveled (the range) d after t seconds into flight are as follows. h= V0 t sin (Theta) - 16t2 d = tv0 cos (Theta) If (Theta) = 30 (Degrees) and the initial velocity is 140 ft/sec what is the following?

You are exploring a planet and drop a small rock from the edge of a cliff. In coordinates where the +y direction is downward and neglecting air resistance, the vertical displacement of an object released from rest is given by y − y0 = 1/2gplanett2, where gplanet is the acceleration due to gravity on the planet. You measure t in seconds for several values of y − y0 in meters and plot your data with t2 on the vertical axis and y − y0 on the horizontal axis.

In an experiment to determine the viscosity of some oil, a ball is dropped into the oil. The position of the ball is given by the formula y(t) = A + Bt +C e−Dt, where y is given in m, and t is the time in s. At t = 0, y(0) = 0.1 m, the y component of the velocity is zero and the y component of the acceleration is ay(0)= 0.04 m/s2.
