Answer:
y maximum 3.54 m, value X 2.35 m
Explanation:
We have a projectile launch problem, let's calculate the maximum height of the projectile, where the vertical speed must be zero
Vyf² = Vyo² - 2g (Y-Yo)
Where Yo is the initial height of the ramp 1.5 m
0 = Vyo² -2g (Y-Yo)
Y-Yo = Voy² / 2g
Y = Yo + Voy² / 2g
Let's calculate the velocity components using trigonometry
Voy = vo without T
Vox = Vo cost
Voy = 7.3 sin 60
Vox = 7.3 cos 60
Voy = 6.32 m / s
Vox = 3.65 m / s
Let's calculate the maximum height
Y = 1.5 +6.32²/2 9.8
Y = 3.54 m
This is the maximum height from the ground
b) They ask us for the position of this point horizontally, we can calculate it looking for the time it took for the skateboarder to reach the highest point
Vfy = Voy - gt
0 = Voy - gt
t = Voy / g
t = 6.32 / 9.8
t = 0.645 s
Since there is no acceleration on the x-axis, we have a uniform movement, we can calculate the distance for this time
X = Vox t
X = 3.65 0.645
X= 2.35 m
A lady bug moves 10 cm forward and 5 cm backwards
so total distance moved by lady bug = 10 + 5 = 15 cm
total time taken by the lady bug
t = 20 s
so the average speed is given as
so its average speed is 0.75 cm/s
It happens when two plates move away from each other.
Answer:
the answer is Saturn
Explanation:
because it is the furthest from the sun
The acceleration of the cart is low with the low fan speed because acceleration depends on speed.
<h3>What was the acceleration of the cart with the low fan speed?</h3>
The acceleration of the cart with the low fan speed is also lower because acceleration depends on the velocity or speed of an object. If speed is lower, the body moves very slow and the acceleration is also low and vice versa.
So we can conclude that the acceleration of the cart is low with the low fan speed because acceleration depends on speed.
