oped from a height H from the floor with the zero initial velocity. The ball is falling under the gravitational acceleration g. If it takes the time t for the ball to hit the floor after it is dropped, can be calculated using the equation, H = gt²/2. ational acceleration is g = 9.81 m/s² with the probable error of 0.19 m/s2, and the time is measured to be t = 0.541 sec with the probable error of 0.021 sec, what is the relative error in mation of the height H?

A golfer launches a tee shot down a horizontal fairway and it follows a path given by r(t) = (at, (85-0.1a)t, - 5t² +60t), where t≥0 measures time in seconds and r has units of feet. The y-axis points straight down the fairway and the z-axis points vertically upward. The parameter a is the slice factor that determines how much the shot deviates from a straight path down the fairway. a. With no slice (a = 0), sketch and describe the shot. How far does the ball travel horizontally (the distance between the point the ball leaves the ground and the point where it first strikes the ground)? b. With a slice (a = 0.2), sketch and describe the shot. How far does the ball travel horizontally (along the y-axis)? c. How far does the ball travel horizontally (along the y-axis) with a = 2.5?
