A falling object accelerates from -10.0 m/s to -30.0 m/s. How much
time does that take?
(Unit = 5)
Remember: Falling = -V
Lost height = -Ay
a = -9.80 m/s2 Be careful with minus signs!!!

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions

Phase changes are chemical changes. true or false

When does your body conduct current more readily?
