Physics: Because the man is slowing down, his velocity decreases over time. Use the final and starting velocities in the data table to calculate his average acceleration. Use the equation , where t is time, ux is initial velocity, vx is final velocity, and ax is acceleration. Use time t = 2.2 seconds, which is calculated using values from the table (2.4 − 0.2).

$the \: ( - )acceleration \: or\\ \: reterdation = \frac{( v_{x} -u_{x}) }{2.2} {m(s)}^{ - 2}$

Explanation:

$if \: initial \: velocity \: = u_{x} \\ if \: final \: velocity \: = v_{x} \\ if \: time \: is \: = 2.2s \\...(since \: displacement \: is \: not \: mentioned) \\ the \: required \: equation \: for \: motion\: is : \\ v_{x} = u_{x} + at \\ a = \frac{( v_{x} -u_{x}) }{t}= \frac{( v_{x} -u_{x}) }{2.2} {m(s)}^{ - 2} \\ \\ note.......you \: did \: not \: provide \: the \: actual \\ value \: of \: v_{x} \: and \: u_{x}. \\ just \: insert \: thier \: values \: in \: the \: above \\\: equation \: i \: proided \: to \: get \: the \: acceleration. \\ the \: value \: of \: this \: acceleration \: should \: be\\ \: negative \: since \: it \: decreses \: with \: time \: (reterdation).$

Similarities:

They were all formed at roughly the same time 4.6 billion years ago. Both Jovian and Terrestrial planets orbit the sun.Both groups have magnetic fields.
