Explanation:
he first PLCs were programmed with a technique that was based on relay logic wiring schematics. This eliminated the need to teach the electricians, technicians and engineers how to program a computer - but, this method has stuck and it is the most common technique for programming PLCs today.
Answer:
The ball will return to the thrower's hand with a speed of 10 m/s
Explanation:
- what is straight upward motion?
It is the motion when an object is projected upward, it moves in the opposite direction of the force of gravity.
The velocity is negative while the object moves up and positive while it moves downward due to upward motion.
Here,
A ball is thrown straight upward, u = 10 m/s
final velocity since ball momentarily stops at highest point, v= 0 m/s
According to Newton's 3rd equation of motion:
where,
g = acceleration due to gravity = -9.8 m/s²
h = height
substituting the values,
2(-9.8)h = (0)² - (10)²
h = 100 / 19.6
h = 5.10 m/s
Now, we consider downward motion:
2gh = v² - u²
where,
g = 9.8 m/s²
h = height = 5.10 m
v = return velocity of ball
u = 0 m/s
substituting the values,
2(9.8)(5.10 m) = V² - (0)²
V = √(99.96)
V = 9.99 m/s
V ≈ 10 m/s
Hence,
the ball will return to the thrower's hand with a speed of 10 m/s

Answer:
5.87 m, 75.5°
Explanation:
Let's say C is the resultant vector.
The x component is the sum of the x components of A and B.
Cx = Ax + Bx
Cx = 10.1 cos 60° + 7.3 cos 275°
Cx = 5.69
The y component is the sum of the y components of A and B.
Cy = Ay + By
Cy = 10.1 sin 60° + 7.3 sin 275°
Cy = 1.47
The magnitude is found with Pythagorean theorem, and the angle is found with trigonometry.
C² = Cx² + Cy²
C² = 5.69² + 1.47²
C = 5.87
θ = atan(Cy / Cx)
θ = atan(5.69 / 1.47)
θ = 75.5°
Answer:
Explanation:
Acceleration is defined as the change in velocity per unit of time
Acceleration (a) = ΔV/t
V = Velocity t = time
ΔV = V₂ - V₁ t = 11s
V₁ = 44m/s
V₂ = 66m/s
ΔV = 66 - 44
= 22m/s
Acceleration (a) = 22/11
= 2m/s²
Displacement (d): Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.
d = v₀ + 1/2*at²
v₀ = 44m/s
a = 2m/s
t = 11s
d = 44 + 1/2*(2 x 11²)
= 44 + 121
d = 165m
