Gpe= 90* 9.81 * 15 = 13243.5 Joules
KE= 13243.5 =1/2 m v^2
v^2= 295.3
v= 17.2 m/s
Hertz Pitch and frequency
Answer:
15m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 40m/s
Time taken = 2s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time;
Acceleration =
Acceleration =
= 15m/s²
