The position of a baseball (in ft) is represented by r(t) = 50 2 ti + (4 + 50 2 t − 16t2)j. Find the arc length of the trajectory (flight) of the baseball. (Let t = 0 represent when the ball is hit. Let j = 0 be ground level. Round your answer to one decimal place.)

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
