Question 4 - If Angelica starts out at 30m/s, and in 16 s speeds up to 84 m/s, what is her acceleration?
1 answer:
Answer:
C.
Explanation:
The acceleration of an object can be found using the equation:
where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
In this problem:
u = 30 m/s is the initial velocity of Angelica
v = 84 m/s is the final velocity
t is the time
Substituting into the equation, we find the acceleration:

From the question given above, the following data were obtained:
Mass of car = 1500 Kg
Initial velocity (u) = 0 m/s
Final velocity (v) = 27 m/s
Time (t) = 8 s
<h3>Acceleration (a) =? </h3><h3>Force (F) =? </h3><h3>1. Determination of the acceleration </h3>Initial velocity (u) = 0 m/s
Final velocity (v) = 27 m/s
Time (t) = 8 s
<h3>Acceleration (a) =?</h3>Therefore, the acceleration of the car is 3.375 m/s²
<h3>2. Determination of the force moving the car.</h3>Mass of car = 1500 Kg
Acceleration (a) = 3.375 m/s²
<h3>Force (F) =?</h3><h3>F = ma</h3>F = 1500 × 3.375
<h3>F = 5062.5 N</h3>Therefore, the force moving the car is 5062.5 N
