Monica is hurrying off to her physics class, jogging down the sidewalk at a speed of 4.10 m/s . Her friend Manny suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 38.5 m above the street level and directly above the sidewalk, to throw them to her. Manny throws them horizontally at a time 4.00 s after Monica has passed below the window, and she catches them on the run. You can ignore air resistance. Part A With what initial speed must Manny throw the bagels so Monica can catch them just before they hit the ground? Hint: The bagels move along a projectile trajectory. Find Monica's location when the bagels reach the ground and demand that the bagels have this same range. When the bagels reach the ground, y_final=0m, and they start at y_initial at hieght of window. Since v_initial has only an x-component, it is straightforward to calculate the time that they will be in the air. You have to add that time onto the jog time. m/s Submit Request Answer Part B Where is Henrietta when she catches the bagels? Vo AEO ? m from the house Submit Request Answer
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
