A cheetah at rest starts running in one direction with the variable acceleration given in the following graph with the solid line (the dotted lines are there to help you read the graph, drawn with my lame drawing technique). Question 4 (10 points) \( \checkmark \) Saved (a) What is the velocity of the cheetah after \( 7.0 \) seconds? Write your answer in \( \mathrm{m} / \mathrm{s} \) with two significant figures. Your Answer: (b) What is the average acceleration of the cheetah between \( t=0.0 \mathrm{~s} \) and \( t=7.0 \mathrm{~s} \) ? Type your answer in \( \mathrm{m} / \mathrm{s}^{2} \) with two significant figures. Your Answer: Answer Question 6 (8 points) (c) If the velocity of the cheetah is instead given by \( v=A t^{3} / x \), where \( t \) is time, \( x \) is position, and \( A \) is a constant, what is the unit of \( A \) in \( S I \) unit? Use regular notation--"/" for divide, "^" for power. For example, if your answer is \( \mathrm{m} / \mathrm{s}^{2} \), type "m/s^2." No quotation marks, no periods, and no space in between letters. A
