Characteristics of a Moving Rocket#

Question Text#

The velocity as a function of time for a rocket is \(v_y(t) =\) , where \(t\) is in seconds and \(v_y\) is in \(m/s\).

Sort the following statements about the position \(y(t)\), velocity, and acceleration \(a_y(t)\) of the rocket at general or specific times into those that are possibly consistent and those that are not possible given this velocity’s time dependence.

Select the statements which are possibly consistent.

Answer Section#

Select all the choices that apply.

Note: You will be awarded full marks only if you select all the correct choices, and none of the incorrect choices. Choosing incorrect choices as well as not choosing correct choices will result in deductions.

  • \(y(t) = -7t^3/3 - 7t^2/2 - 4.6\)

  • \(v_y(t=\) 9.8\(s) = \) -740.88 \(m/s\)

  • \(a_y(t) = -6t^3 + t^2\)

  • \(v_y(t=\) 9.8\(s) = \) -54.088 \(m/s\)
