Wayne Gretzky is arguably the greatest hockey player of all time. He holds many individual including the NHL career record for points scored. If Gretzky shoots the puck at a speed of 90km/h from the top of the offensive face-off circle 15 m from the net, how long will the puck take to reach the net? __ S (Round and record your answer to two significant digits) Some of the fastest moving arachnids are the long -legged Sun spiders (genus Solpuga) found in semi-desert areas throughout the world. These spiders are capable of moving up to 16km/h Use the following information to answer the next two questions 10. Moving at maximum speed, what is the shortest time it would take a Sun Spider to run between two fig trees that are 3.6 m apart? a. 0.23 s b. 14 s c. 1.5 s d. 0.81 S Numerical cal Response

## Step 1: Convert units### We need to convert the speed from km/h to m/s. We know that 1 km = 1000 m and 1 hour = 3600 seconds. Therefore, . Similarly, .## Step 2: Calculate the time for the puck to reach the net### We are given the distance (15 m) and the speed (25 m/s). Time is calculated as distance divided by speed: .## Step 3: Calculate the time for the sun spider to travel between the fig trees### We are given the distance (3.6 m) and the speed (4.44 m/s). Time is calculated as distance divided by speed: .
