Which of the following expressions does not have the correct dimensions for calculating the time it takes an object to fall to the ground? Force has dimensions of ? ⋅ ?/?2
a. volume/ (area x speed)
b. distance/ speed
c. √distance x mass / force (square root over the whole equation)
d. velocity / acceleration
e. area/acceleration The answer is E, but I do not understand how it is not B. Please show the dimensions for each. Thank you

An object of mass 700 kg is released from rest 1000 m above the ground and allowed to fall under the influence of gravity. Assuming the force due to air resistance is proportional to the velocity of the object with proportionality constant b=50 N-sec/m, determine the equation of motion of the object. When will the object strike the ground? (Hint: Here the exponential term is too large to ignore. Use Newton's method to approximate the time t when the object...

Part C Find the dimensions [v] of speed. Express your answer as powers of length (/), mass (m), and time t View Available Hint(s) 11에 Submit There are three dimensions used in mechanics: length (), mass (m), and time (t). A combination of these three dimensions suffices to express any physical quantity, because when a new physical quantity is needed (e.g., velocity), it always obeys an equation that permits it to be expressed in terms of the...
