Answer:
<em>It takes 3 seconds to reach its high point</em>
Explanation:
<u>Projectile Motion</u>
In a projectile motion (or 2D motion), the object is launched with an initial angle θ and an initial velocity vo.
The components of the velocity are
The speed in the horizontal direction at any time t is:
The time taken to reach the maximum height is when vy=0, or:
We are given the y-component of the velocity, thus:
It takes 3 seconds to reach its high point
Answer:
4.78 kg/m^2.
Explanation:
τ = Iα
Where,
τ = torque, around a defined axis (N∙m)
I = moment of inertia (kg∙m2)
α = angular acceleration
= 1.2 rad/s^2
τ = F * r
= 16.88 * 0.34
= 5.74 N.m
Therefore, I = 5.74/1.2
= 4.78 kg/m2
Answer:
A)
Explanation:
Energy transformation is when energy changes from one form to another.
FOCAL LENGTH = 9.5cm
i° e° d°
30 43 69
40 41 61
45 39 56
50 37 48
65 41 37
plot a graph of d° against i°
from the graph Determine;
(i) the minimum deviation and the corresponding angle of incidence
(ii) the maximum deviation and the corresponding angle of incidence
n=sin(A+D÷2)÷(sinA÷2)
Determine the error in n and explain why it is not advisable to use small values of i° in performing this experiment.
