$2.$ The determined coyote $($Road$-$Runnerus Digestus$)$ is out once more in pursuit of the elusive roadrunner $($Velocitus Tremenjus$).$ This time he acquires an Acme jet motor providing a constant acceleration of $\backslash (25\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}^\{2\}\backslash ).$ The coyote starts his jet motor $150$ m before the edge of a cliff at the instant the roadrunner zips past him. At the edge of the cliff, the roadrunner escapes by making a sudden turn, while the coyote continues straight ahead $($he$\text{'}$ll never learn$).$ His jet motor remains horizontal and continues to operate while he is in flight.
