Answer:
An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving

Explanation:
Find the time it takes for the roadrunner to land.
Given (in the y direction):
Δy = 0 m
v₀ = v sin 10°
a = -9.81 m/s²
Find: t as a function of v
Δy = v₀ t + ½ at²
(0 m) = (v sin 10°) t + ½ (-9.81 m/s²) t²
t = (v sin 10°) / 4.905
Given (in the x direction):
Δx = 20.5 m
v₀ = v cos 10°
a = 0 m/s²
Find: t as a function of v
Δx = v₀ t + ½ at²
(20.5 m) = (v cos 10°) t + ½ (0 m/s²) t²
t = 20.5 / (v cos 10°)
Set equal and solve for v:
(v sin 10°) / 4.905 = 20.5 / (v cos 10°)
v² sin 10° cos 10° = 100.5525
v = 24.2485398301588

None of the options shown are correct.
Answer:
I = 0.2 A
Explanation:
The current flowing across each resistor in a series arrangement is the same throughout the circuit. So in order to calculate the current, we must first find the equivalent resistance of all three resistors. The equivalent resistance of the resistors connected in series is given as:
Now we use Ohm's law for the current:
<u>I = 0.2 A</u>
Answer:
<h3>The answer is option A</h3>
Explanation:
To find the mass of an object given it's acceleration and the force acting on it we use the formula
From the question
force = 500 N
acceleration = 5.0 m/s²
We have
We have the final answer as
<h3>100 kg</h3>
