As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 37.0 m/sm/s.How fast is the watermelon going when it passes Superman?
As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 30.0 m/s . How fast is the watermelon going when it passes Superman?
The fastest slapshot recorded was by Al lafrate in
1993 at 169.3 km/h. Assume this is the average speed of
the puck as it travels from the blue line to the goal, a
minimum distance of 18.3 m (60 feet). How long does the
goalie have to react to the shot? (Average human reaction
time is roughly 0.15 s)
