Answer: It's the third one.
Explanation:
The uniform acceleration of the car is 4.485 m/s².
<h3>
Acceleration of the car</h3>
The uniform acceleration of the car is calculated as follows;
v² = u² + 2as
a = (v² - u²)/2s
where;
- v is final velocity = 41 m/s
- u is initial velocity = 28 m/s
- s is distance = 100 m
- a is acceleration = ?
a = (41² - 28²)/(2 x 100)
a = 4.485 m/s²
Thus, the uniform acceleration of the car is 4.485 m/s².

Answer:
given,
R = 2i + j+3k
a) magnitude in x = 2
y = 1
z = 3
b) magnitude of R
R = 3.74 units
c) angle between the R and the x, y, and z axes.
θ x = 57.72°
θ y = 74.51°
θ z = 36.68°
