01: If a car is traveling at (80 km/h), determine its speed in miles per hour and foots per second.

1. Kenny is climbing the stairs of his apartment building for exercise. Kenny weighs 83 kg. There are 8 steps in each flight and the height of a single step on the staircase is 11 inches. He climbs the flight of stairs in 3.4 seconds.  a.) calculate the long-term rate at which stairs can be climbed considering the given information.(how long can be sustained in stair per second) b.) Why does Kenny descend stairs at a faster rate for a nearly unlimited time although very similar forces are exerted descending as they are ascending?(This points to a fundamentally different process for descending versus climbing stairs.)

A bird flies north at 20m/sec for 15 sec. it rest for 5 sec and then flies south at 25 m/sec for 10 sec. for the whole trip, what .is the average speed

The speed S (m/mii) of an object is defined by S = 6t² + 2t + 3 after t minutes. For the first one minute, the object travelled for 10 m. Determine how far the object travelled for the first two minutes. O 25 O 40 O 20 O 30
