The elastic potential energy of the spring is 0.31 J
Explanation:
The elastic potential energy of a spring is given by

where
k is the spring constant
x is the compression/stretching of the spring
For the spring in this problem, we have:
k = 500 N/m (spring constant)
x = 0.035 m (compression)
Substituting, we find the elastic potential energy:

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:

Answer:
the acceleration of the car is 1.167 m/s²
Explanation:
Given;
initial velocity of the race car, u = 5 m/s
final velocity of the race car, v = 12 m/s
time to finish the race, t = 6 s
The acceleration of the car is calculated as;
a = (v - u) / t
a = (12 - 5) / (6)
a = 1.167 m/s²
Therefore, the acceleration of the car is 1.167 m/s²
