A proton initially has v = 5.01-1.0 +7.0k and then 4.0 s later has v = -3.01-1.0 +8.0k (in meters per second). (a) For that 4.0 s, what is the proton's average acceleration avg in unit-vector notation? -2 m/s+0 m/s2 +0.25 (b) For that 4.0 s, what are the magnitude and direction of aavg? 2.016 m/s (from the +x axis in the xz plane) m/s k 5. [1/2 Points] DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A certain airplane has a speed of 80.0 m/s and is diving at an angle of 30.0 below the horizontal when the pilot releases a radar decoy (see figure below). The horizontal distance between the release point and the point where the decoy strikes the ground is 700 m. (Neglect air resistance.) 30.0 700 m (a)..How.high was the plane when the decoy was released? m Enter a number. (b) How long was the decoy in the air? 10.104 Submit Answer S 9.

The ball leaves the bat at an angle of 45 with the ground. With that launch, the ball should have a horizontal range (returning to the launch level) of 107 m. (a) Does the ball clear a 10.87-m-high fence that is 97.5 m horizontally from the launch point? Yes No ..(b)..What is the distance between the top of the fence and the center of the ball when the ball reaches the fence? Enter a number. x m You kno angle and range and can find the launch speed. Then, as a second calculation, you know the launch angle and speed and want the height (above launch level) at a certain horizontal distance. To that height you must add the given height of launch.
