Review Constants A robot arm must accelerate to be extended. Constant-acceleration motion is simple to analyze but rarely applies in the real world because acceleration cannot be instantly turned on and off. Robot designers have found that motion can be both practical (implemented by software and real motors) and sufficiently smooth if it has constant jerk. Just as velocity is the time derivative of position and acceleration is the time derivate of velocity, jerk is defined to be the time derivative of Part B Suppose a robot arm, initially at rest, is extended for 0.50 s witha constant jerk of 19 m/s3. What is the arm's forward velocity at the end of this interval? Express your answer with the appropriate units. • View Available Hint(s) da, is the rate of dt acceleration. That is, jerk jz = change of acceleration, a name that comes from the fact that motion with a changing acceleration can be quite jerky. Motion with constant jerk is motion in which the acceleration has a constant rate…

4. Swims across Lake Erie are officially sanctioned by the Lake Erie Open Water Swimming Association. Your friend on the swim team wants to swim across the lake. The plan is that your friend will swim to Presque Isle starting at a location at Long Point, Ontario which is 24 miles due north of Presque Isle. You will be navigating a boat with a GPS. Your friend can maintain a speed of 1.80 mph in still water. All during the swim you observe that objects drifting in the water are moving at 0.70 mph to the east due to the current. a. What bearing should you maintain? That is what direction should you point the boat to reach Presque Isle? Give your answer relative to a compass direction (i.e., 30° north of west). Hint, you want your net velocity vector to be straight south. b. How long did it take your friend to swim across Lake Erie? c. What is the addition amount of time that your friend will need to swim compared to if there was no current (assume your friend swims at a constant rate)?

Current Attempt in Progress A Boeing 747 "Jumbo Jet" has a length of 59.7 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.9 m. The plane decelerates through the intersection at a rate of 6.18 m/s2 and clears it with a final speed of 42.1 m/s. How much time is needed for the plane to clear the intersection?

A vehicle is moving at +36.0 m/s when the driver sees a stop sign. In 2.60 seconds, the vehicle comes to a stop. 1) Find the vehicle’s acceleration (magnitude and direction). 2) Find the vehicle’s displacement (magnitude and direction).
Lesson: Projectiles When there is air resistance present how to the velocity and acceleration vectors behave? O The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it. O The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory O The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory O The acceleration and velocity vectors are both constant magnitude but continually change direction.
