Answer:
1.3m/s²
Explanation:
Given parameters:
Distance = 100m
Time taken = 9.58s
Final speed = 12.43m/s
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time; to solve this problem, we apply one of the motion equation;
v = u + at
v is the final speed
u is the initial speed
a is the acceleration
t is the time
u = 0m/s
Insert the parameters and solve;
12.43 = 0 + a x 9.58
12.43 = 9.58a
a = [tex]\frac{12.43}{9.58}[/tex] = 1.3m/s²
