<u>Answers</u>
same distance from the mirror as the object
same size
lateral inversion
<u>Explanation</u>
The image formed by a plane mirror is formed at equal distance from the mirror as the object is.
The size of the image is the same as the size of the object.
The image is laterally inverted. This means that, when a person lifts his right hand, his or her image will raise it's left hand.
Answer:
(a)
(b) 157.76679 m
(c) 17.62757 m/s
Explanation:
Net force acting,
Acceleration, where m is the mass
(b)
From kinematic equation
where s is displacement, u is initial velocity, t is time taken and a is acceleration.
Considering that u=0 since it starts at rest
and substituting the value of a as calculated in part a, t is 17.9 s hence
(c
)
From kinematic equation
v=u+at where u and v are initial and final velocities respectively, a is acceleration and t is duration in seconds. Since it starts from rest, u=0 and substituting the value of a as found in part a, t given as 17.9 s we get
V=0+0.984781*17.9=17.62757 m/s
1. It will take 0.45 s for the bowling ball to fall 1 m
2. it will take 0.45 s for the ping pong ball to fall 1 m
<h3>Data obtained from the question</h3>
From the question given above, the following data were obtained:
- Height (h) = 1 m
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) =?
<h3>How to determine the time taken to fall</h3>
The time taken for the bowling ball to fall can be obtained as illustrated below:
h = ½gt²
1 = ½ × 9.8 × t²
1 = 4.9 × t²
Divide both side by 4.9
t² = 1 / 4.9
Take the square root of both side
t = √(1 / 4.9)
t = 0.45 s
Thus, it will take 0.45 s for the bowling ball to fall.
Considering the ping pong ball, it will also take 0.45 s to fall 1 m since the same gravity is acting on it
