Answer:
-2040 m/s²
Explanation:
Taking toward the wall to be positive, the initial velocity is 10.1 m/s and the final velocity is -8.3426 m/s.
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (-8.3426 m/s − 10.1 m/s) / 0.00905 s
a = -2040 m/s²
A
A charge moving through an electric circuit would gain electric potential energy in the internal circuit and lose electric potential energy in the external circuit. Charge has the greatest amount of electric potential energy at the - terminal of the battery.

Below is an attachment containing the solution.
Complete Question
A boy throws a ball on a spring scales which oscillates about the equilibrium position with a period of T = 0.5 sec. The amplitude of the vibration is A = 2 cm. Assume the ball does not bounce from the scales’s surface afterwards. Assume the vibration of the scale is expressed mathematically as x(t) = Acos(t + ). Find:
a) frequency
b) the maximum acceleration
c) the maximum velocity
Answer:
a
b
c
Explanation:
From the question we are told that
The period is
The amplitude is
The vibration of the scale is
Generally the frequency is mathematically represented as
=>
=>
The maximum acceleration is mathematically represented as
=>
=>
The maximum velocity is mathematically represented as
=>
=>
if it is accelerating, there's an unbalanced force
