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.
Locusts can jump to heights of 0.660m.
(a). Assuming the locust jumps straight up, and ignoring air resistance, what is the takeoff speed of the locust?
(b). The locust actually jumps at an angle of abut 55.0 degrees above the horizontal, and air resistance is not negligible. The result is that the takeoff speed is about 40.0% higher than the value you calculated in part (a). If the mass of the locust is 2.00 g and its body moves 4.00cm in a straight line while accelerating from rest to the takeoff speed, calculate the acceleration of the locust (assumed constant).
(c) The locust actually jumps at an angle of abut 55.0 degrees above the horizontal, and air resistance is not negligible. The result is that the takeoff speed is about 40.0% higher than the value you calculated in part (a). If the mass of the locust is 2.00 g and its body moves 4.00cm in a straight line while accelerating from rest to the takeoff speed, estimate the force exerted on the hind legs by the ground(Ignore the locust's weight).
(d) The force exerted on the hind legs by the ground is ________ times that of the locust's weight
