Acceleration is a vector quantity that is defined as ❝ rate of change in velocity ❞
And as per the question, the plane can go from 0 miles to 100 miles/hour in 10 seconds that shows rate of change in its velocity. that is :
from 0 miles/hour to 100 miles/hour. hence Acceleration is the quantity being described about the new plane.
[ v = final velocity, u = initial velocity, t = time ]
So, the Acceleration of the new plane is 10 miles/hour²
Answer:
Kinetic energy at 0.05 m is 0.037 J
Explanation:
Given:
Mass, m = 2 kg
Spring constant, k = 10 N/m
Amplitude, A = 0.1 m
Angular frequency, ω = √k/m
Substitute the suitable values in the above equation.
ω = 2.24 s⁻¹
Simple harmonic equation is represent by the equation:
x = A cos ωt
Substitute 0.05 m for x, 0.1 m for A and 2.24 s⁻¹ for ω in the above equation.
t = 0.47 s
Kinetic energy at x = 0.05 is determine by the relation:
Substitute the suitable values in the above equation.
E = 0.037 J
