A canno baii is fired at a velocity of 25 m.s. Calculate: 2. the maximum height that it reaches. 2.2 the time elapsed until it returns to the same horizontal level as the top end of the cannon barrel, from where it was fired. 2.3 at which height above the ground the cannonball has an upwards velocity of 10 m.s (assume the barrel is 1 m above the ground).
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.
![estion 2
A canno bail is fired at a velocity of 25 m.s. Calculate:
2. the maximum height that it reaches.
2.2 the time elapsed until it returns to the same horizontal level as the top end of
the cannon barrel, from where it was fired.
2.3 at which height above the ground the cannonball has an upwards velocity of
10 m.s (assume the barrel is 1 m above the ground).

Question 3
A hot-air baiioon travels upwards at a constant velocity. At a height of 80 m above
the ground, someone drops his cell phone from the balloon. It hits the ground
after 5 seconds. Ignore the effect of air resistance.
3.1 Calculate the velocity at which the balloon travels upwards.
3.2 Calculate the maximum height above the ground reached by the cell phone.
3.3 How long after the cell phone falls, does it pass the point from where it
started to fall?
3.4 How iong after the cell phone has been dropped, does the distance between
the balioon and the cell phone equal 20 m?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0cf86f97-418c-4d6e-9446-f7995707a29c%2Fffb47037-3ba9-4c36-a9e0-6aaf226329ab%2Fmnza485_processed.jpeg&w=3840&q=75)
