An aircraft makes a horizontal circular turn. The air craft enters the turn with velocity of v = 300i+400j, 20 seconds later it leaves the turn with velocity of v = 400i - 300j. Determine the acceleration of the aircraft in g units.

Waves that cause the most damage during an earthquake are a. surface waves c. s waves b. p waves d. ocean waves

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

If an astronaut takes an object to the moon the following is true (choose only one). a the mass will change but the weight will be the same. b both the mass and the weight of the object will be the same. c the weight will change but the mass will be the same. d both the mass and the weight of the object will change.
