The spring constant, k will be 18 N/m.The ratio of force to one unit of displaced length is known as the spring constant.
What is the spring constant?Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant,K=?
The formula for the spring constant when the spring is oscillate at the given amplitude A:
[tex]\rm K = \frac{V_{max}^2 m}{A} \\\\ K = \frac{3.0 \times 0.250}{0.125} \\\\ K=18 \ N/m[/tex]
Hence, the spring constant, k will be 18 N/m

An aircraft lands and brakes, slowing from 250 m/s to 5 m/s in 30 secs. What is it's acceleration?
O-10 m/s²
-8.2 m/s²
-1.3 m/s²
-5.2 m/s²
The acceleration of the aircraft is determined as -8.2 m/s².
Acceleration of the aircraft
The acceleration of the aircraft is calculated as follows;
a = Δv/t
where;
Δv is change in velocityt is timea = (5 - 250)/(30)
a = -8.2 m/s²
Thus, the acceleration of the aircraft is determined as -8.2 m/s².

A car travels 263.0 miles in 5.5 hours. How long will it take to travel 363.0 miles at
this average velocity? (Answer to 1 decimal place)
From the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.
How long will it take to travel 363.0 miles at the given average velocity?Note that; Velocity is the speed at which an object moves in a particular direction. It is expressed as;
v = distance / time
Given that;
Distance covered by the car d = 263.0 milesTime elapsed t = 5.5 hoursFirst we determine the velocity of the car.
v = distance / time
v = 263.0 miles / 5.5 hours
v = 47.8181 miles per hour.
Now, if the car travels 363.0 miles, time elapsed will be;
velocity = distance / time
time = distance / velocity
time = 363.0 miles / 47.8181 miles per hour
time = 7.6 hours
Therefore, from the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.
