Answer:
U=4m/s
V=6m/s
T=5s
Acceleration =v-u/t
6-4/5
=2/5 metre/second(square).
Answer:
2.05 kgm²/s
Explanation:
I = moment of inertia of cylinder = 0.016 kgm²
r = radius of the cylinder = 6 cm = 0.06 m
v = linear speed of the cylinder = 7.7 m/s
w = angular speed of cylinder
Using the equation
v = r w
7.7 = (0.06) w
w = 128.33 rad/s
Magnitude of angular momentum of the cylinder is given as
L = I w
L = (0.016) (128.33)
L = 2.05 kgm²/s
The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.
<h3>
What is vertical motion of a projecile?</h3>
The vertical motion of a projectile is affected by gravity and the velocity of vertical motion given by the following formula;
Vy = Vsinθ
<h3>
What is horizontal motion of a projecile?</h3>
The horizontal velocity of a projectile is given by the following formula;
Vx = Vcosθ
<h3>Direction of the motion</h3>
The direction of the motion is calculated as follows;
tanθ = Vy/Vx
Thus, the formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.
