V₀ = 5,0 m/s
V = 7,5 m/s
t = 1,25 s
_________
a = (V-V₀) / t = (7,5 - 5,0 ) / 1,25 = 2,50 / 1,25 = 2 m/s²
Answer: acceleration a=2 m/s²
Answer:
T = 0.83 seconds
Explanation:
Given that,
The mass attached to the spring, m = 1.5 kg
The amplitude of the spring, A = 0.3 m
The spring constant of the spring, k = 85 N/m
We need to find the period of the mass's motion. The time period in spring mass system is given by :
So, the period of the mass's motion is 0.83 seconds.
Average speed = total distance / total time.
That's 172 km / 5 hr = 34.4 km//hr
