A horse canters away from its trainer in a straight line, moving 140 m away in 16.0 s. It then turns abruptly and gallops halfway back in 5.0 s. (a) Calculate its average speed. (b) Calculate its average velocity for the entire trip, using "away from the trainer" as ...

Physics
When two vectors vector A and vector B are drawn from a common point, the angle between them is phi. If vector A and vector B have the same magnitude, for which value of phi will their vector sum have the same magnitude as vector A or vector B?

A helicopter is ascending vertically with a speed of 5.50 m/s. At a height of 155 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground? [Hint: The package's initial speed equals the helicopter's.]

A baseball is hit nearly straight up into the air with a speed of 24 m/s. (a) How high does it go? (b) How long is it in the air?

what assumption have you made in performing the free fall lab experiment and analyyzing the results?

PHY
Express the direction 331° CW from the +x-axis in the following different ways. For this problem north is positive y and east is positive x. 1) east of north 2) above the +x-axis 3) right of the vertical in quadrant 1 4) CW from the -y-axis

PHY
Vector V1 is 9.00 units long and points along the negative x axis. Vector V2 is 4.72 units long and points at +50.0° to the +x axis. (a) What are the x and y components of each vector? V1x = V1y = V2x = V2y = (b) Determine the sum V1 + V2. Magnitude AND Direction (counter...
