A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon. O 1.67 s O 0.535 s O 1.54 s O 1.29 s

X An object velocity decreases from 15m/s to 10m/s in 2s. It's deceleration 0/1 is * 2.5 m/s^2 5 m/s^2 7.5 m/s^2 12.5 m/s^2

Use the following data to calculate the velocity and acceleration of a free falling object.  The object is 45 meters above the ground and free falls to the earth.   Time   seconds Distance   meters Average Velocity m/s Final Velocity m/s Acceleration   m/s2 0.000 0.000 0 0 0 0.250 0.306       0.500 1.23       0.750 2.76       1.00 4.90       1.25 7.65       1.50 11.0       1.75 15.0       2.00 19.6       2.25 24.8       2.50 30.6       2.75 37.1       3.00 44.1       Calculate the Average Velocity using  Average Velocity = Distance/Time. Calculate the Final Velocity using  Final Velocity = 2 x Average Velocity. Calculate the Acceleration using Acceleration = Final Velocity/Time. How do the values compare to the known value of "g"?

Assume that an MX missile goes from rest to a suborbital velocity of 5.5 KM/ S in 40.0 seconds. What is the average  acceleration in m/s^2m M/s^2 What is the average acceleration in multiples of g? G

The next few questions challenge you to figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 76.1 m above the ground, and the stone hits the ground 6.17 s later. What is the value of g on Planet #1?     24.67 m/s^2     4.00 m/s^2     2.00 m/s^2     12.33 m/s^2

Maria needs to travel to her sister's home, 285 km away, in 4.0 hours. The first 60 km  she can only travel at 40.0 km/ hr. What will her average speed need to be for the remainder of the trip in order to make it in time?

A 200-g box slides across a frictionless plane inclined at 30 degrees with respect to the horizontal. What is is its acceleration in m/s2? M F 30° O 9.8 O 8.48 O 4.9 O 12
