Answer:
a) y = 162.6 m
, b) R = 928.64 m
Explanation:
We will solve this exercise using projectile launch kinematics, as the initial velocities and angle are equal on the planet and the Earth, let's look for the gravedd coinage of the planet
Earth
R = v₀² sin 2θ / g
R g = v₀² sin 2θ
In the planet
4.8 R = v₀² sin 2θ /
4.8 R = v₀² sin 2θ
4.8 R = R g
= g / 4.8
= 9.8 / 4.8
= 2.04 m / s²
Now we can answer the questions
a) The maximum height
Vy² = ² - 2 g y
For ymax the vertical speed is zero ( = 0)
sin θ = /
= sinθ
= 44.9 sin 35
= 25.75 m/s
y = ²/2
y = 25.75² / (2 2.04)
y = 162.6 m
b) the scope
R = v₀² sin 2θ /
R = 44.9² sin 2 35 / 2.04
R = 928.64 m
It falls between Step
2) Research & Step 4) Test with an Experiment.
Explanation:
The primary steps of the scientific method are 1) perform an investigation that describes a problem, 2) generate a hypothesis, 3) examine the hypothesis, 4) draw conclusions and refine the hypothesis.
What's the answer choices?
Answer:
94 kg or 921.6 N
Explanation:
The velocity function is . The acceleration function, a(t), is the time derivative of the velocity function.
At ,
Because the elevator is going upwards, the net acceleration, where g us acceleration of gravity.
The resultant weight is
Since the bathroom scale is graduated in kg, it's reading is
