**Physics Problem: Free Fall on a Different Planet**An object falls freely from rest on a planet where the acceleration due to gravity is \(18 \, \text{m/s}^2\).After \(3.9 \, \text{s}\), what will be its speed? Answer in units of \(\text{m/s}\).**Solution Explanation:**To find the speed of the object after \(3.9 \, \text{s}\), use the formula for velocity in free fall:\[ v = u + at \]where:- \( v \) is the final velocity,- \( u \) is the initial velocity (which is 0 since the object starts from rest),- \( a \) is the acceleration (\(18 \, \text{m/s}^2\) in this case),- \( t \) is the time in seconds (\(3.9 \, \text{s}\)).Plugging in the values:\[ v = 0 + (18 \, \text{m/s}^2)(3.9 \, \text{s}) \]\[ v = 70.2 \, \text{m/s} \]Thus, the speed of the object after \(3.9 \, \text{s}\) will be \(70.2 \, \text{m/s}\).

A dog initially at rest, starts running inside a circular track with a 40π m circumference. The dog's acceleration tangent to its path is defined by the function at = 0.1t2 + 0.4t. What is the total distance ran by the dog after t = 10 s?
You are working part-time for the GT Sports Media Complex, editing video for the women’s softball team. In one particular clip, a GT player hits a home run over the center field fence. The ball leaves the bat at a height of 4 ft, and crosses the outfield fence (220 ft away) at a height of 10 ft. Logs of the game indicate that the pitch was clocked at 68 mph as it reached the plate. Your frame-by-frame analysis of the 30-frame-per-second video indicate that the ball spent only a single frame in contact with tha bat, and another 126 frames travelling to the outfield fence.
