Answer:
<em>a. The rock takes 2.02 seconds to hit the ground</em>
<em>b. The rock lands at 20,2 m from the base of the cliff</em>
Explanation:
Horizontal motion occurs when an object is thrown horizontally with an initial speed v from a height h above the ground. When it happens, the object moves through a curved path determined by gravity until it hits the ground.
The time taken by the object to hit the ground is calculated by:
The range is defined as the maximum horizontal distance traveled by the object and it can be calculated as follows:
The man is standing on the edge of the h=20 m cliff and throws a rock with a horizontal speed of v=10 m/s.
a,
The time taken by the rock to reach the ground is:
t = 2.02 s
The rock takes 2.02 seconds to hit the ground
b.
The range is calculated now:
d = 20.2 m
The rock lands at 20,2 m from the base of the cliff
Main answer- the velocity of 2.2kg ball is 12.566m/s
supporting answer- In circular motion the velocity is termed as angular velocity
Angular velocity represents the rate of variation of an object's position angle with respect to time.
W =theta/ time
W = length of the arc/ radius of circle × time
body of the answer-2πr/r×t =2π/t
2×π/ 0.5 = 12.566 m/s
final answer- hence the velocity of ball is revolving is 12.566 m/s

The radial force on the particle is given by the Lorentz force. They don't give you the velocity so you have to solve for it in terms of the radius and get them to cancel.
