Find the time that the arrow spends in the air.

Suppose someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree. How long after the arrow was shot should the apple be dropped, in order for the arrow to pierce the apple as the arrow hits the tree?

Part A = 0.4018 m/s

Part B = 75.43 °

After a package is ejected from the plane, how long will it take for it to reach sea level from the time it is ejected? Assume that the package, like the plane, has an initial velocity of 260 mph in the horizontal direction.

If the package is to land right on the island, at what horizontal distance D from the plane to the island should the package be released?

What is the speed v_{f} of the package when it hits the ground?

A swimmer wants to cross a river, from point A to point B, as shown in the figure.

To swim directly from A to B, what speed u_{s}, relative to the water, should the swimmer have?

Part A = -6.00m/s

Part B = 10.4m/s

Part C = The vertical component exhibits motion with constant nonzero acceleration, whereas the horizontal component exhibits constant-velocity motion

Part D = 1.0s

Part E = 3.0m/s

Consider a particle with initial velocity *v* that has magnitude 12.0m/s and is directed 60.0 degrees above the negative x axis.

Look at this applet. The motion diagram for a projectile is displayed, as are the motion diagrams for each component. The x component motion diagram is what you would get if you shined a spotlight down on the particle as it moved and recorded the motion of its shadow. Similarly, if you shined a spotlight to the left and recorded the particle’s shadow, you would get the motion diagram for its y component. How would you describe the two motion diagrams for the components?
