Answer:
a = 2 m/s^2
which agrees with the third answer option provided.
Explanation:
Recall the kinematic formula for displacement under the action of a constant acceleration "a":
yf - yi = 1/2 a t^2
using the information provided this equation becomes:
9 = 1/2 a (3)^2
solve for a:
9 * 2 / 9 = a
then a = 2 m/s^2
which agrees with the third answer option provided.

Explanation:
Got it right on edge
Let's solve ~
Given terms :
The formula to find kinetic Energy is ~
Now, apply the formula according to given situation
Therefore, the kinetic Energy of the car is 56 joules
Explanation:
1.
Initial speed of satellite is 30,000 m/s
Final speed of satellite is 15000 m/s
Time taken by the satellite to reach final speed is 60 s
The satellite’s acceleration is equal to the change in velocity divided by time taken. So,
2.
Initial speed of a boat is 42 m/s
Final speed of a boat is 88 m/s
Time taken is 4 s
The acceleration of boat during this period is :
Answer:
F = 3.86 x 10⁻⁶ N
Explanation:
First, we will find the distance between the two particles:
where,
r = distance between the particles = ?
(x₁, y₁, z₁) = (2, 5, 1)
(x₂, y₂, z₂) = (3, 2, 3)
Therefore,
Now, we will calculate the magnitude of the force between the charges by using Coulomb's Law:
where,
F = magnitude of force = ?
k = Coulomb's Constant = 9 x 10⁹ Nm²/C²
q₁ = magnitude of first charge = 2 x 10⁻⁸ C
q₂ = magnitude of second charge = 3 x 10⁻⁷ C
r = distance between the charges = 3.741 m
Therefore,
<u>F = 3.86 x 10⁻⁶ N</u>
