A space vehicle accelerates from six second from rest to a speed of 95 m/s. it travels at that speed for another ten seconds.
1. What was its acceleration?
2. What is the total distance it went in all 16 seconds?
3. Assume a second space vehicle accelerates at half the rate of acceleration as the first rocket. It also has a maximum speed of 95 m/s. how far does it get in 16 seconds?
A feather is dropped on the moon from a height of 3 meters. Determine the time for the feather to fall to the surface of the moon
A sinusoidally varying voltage is represented by V(t) = (75 V)sin(120?t). What are its frequency and peak voltage
An airplane passes over a checkpoint and flies 10 kilometer east, then 5 kilometer north, then 10 kilometer North West. Compute how far is the airplane from the original checkpoint

During 9.93 seconds a motorcyclist changes his velocity from v1,x = -37.3 m/s and v1,y = 14.1 m/s to v2,x =-21.9 m/s and v2,y = 29.3 m/s. Find the components of the motorcycle's average acceleration during this process, aav,x and aav,y.

Consider a simple model of the hydrogen atom where one electron is in a stable orbit around one proton at a distance of 0.05 nm. If the electron were moved to a larger stable orbit (say 0.1 nm), what would be the sign of: delta U = the change in pote..
Demonstrate that gravitational energy is not extensive: show that the gravitational energy of a sphere of radius 'r' and uniform density varies with volume V^n and find the exponent 'n'.
Let us assume that the winter consists of 150 days in which the outside temperature is 0C. This will give the typical number of "heating degree days" observed in a winter along the northeastern US seaboard.
