A cannon barrel is 1.2 m long. A cannonball (20 kg) is fired horizontally off ofa 10 m tall cliff. The cannonball hits the ground at a range of 200 m. a) Find the velocity of the cannonball when it leaves the cannon. (A: 140£– ) b) Find the constant acceleration that was applied to the cannonball. (A: 8167£ ) c) How much constant force was applied to the cannonball while it was in the barrel of the cannon? (A: 163,333£ N)
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.
Write the given values with suitable variables.
Here, L denotes the barrel length, m denotes the mass, h denotes the height, and d denotes the horizontal distance.
