This weekend I observed a squirrel running across the roof of the my house. The squirrel attempted to jump to a tree. The poor squirrel had bad luck and fell short of the tree. I am happy to report that the squirrel was unharmed and landed on the ground safely. The mathematician in me analyed the situation and came up with the following: Let: h= squirrel (ft) t-time (sec) Equation: h=-161²+ 10t + 18. 1. At 0.313 seconds, the squirrel reaches the peak of her trajectory. How high was the squirrel before she began to fall? 2. How high was the squirrel before she jumped? 3. About how long was the squirrel in the air (from the time she left the roof to hitting the ground?) (When would h= 0 ft)

helpp....i did half

When Alex rides his dirt bike off a ramp, his path can be modelled by h(d) = -3.9d + 13.ld + 8.7, where dis the horizontal distance from the ramp and h is the height, both in metres. How far away from the ramp does he land, to the nearest tenth of a metre?

Steven's Cat Math: This weekend I observed a cat, known as Fluffy, running across a branch and attempting to jump up to another tree. Unfortunately, Fluffy missed the other tree and fell to the ground. Luckily, Fluffy was uninjured! The mathematician in me analyzed the situation and came up with the following: Let: h= Fluffy (m) t=time (sec) Equation: h = -9.8(m/sec)t² + 5(m/sec)t + 11(m) h = OR - 9.8t² + 5t + 11 1) At 0.255 seconds, Fluffy reaches the peak of his trajectory. How high was fluffy before he began to fall? 2) How high was Fluffy before he jumped? 3) About how long was Fluffy falling before reaching the ground? (When would h=0 ft?) # (How to plot in graph) 4) Using the information from questions #1-3, sketch the graph the represents the Fluffy's height vs. time. Label your both axes, 10 5 0 0,5 5) From the equation, how fast was Fluffy running when he jumped? 15 2
