If the spring's initial position is 0.098 meters from the origin, and the spring is continually displaced to a position of 0.299 meters from the
origin (Wall) with the required applied Force of 84.5 Newtons by the
block, causing it to accelerate constantly at 7.399 meters per second
squared, what is the spring constant k? ROUND answers to 1 decimal
place, NO UNITS!!!

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

It equals just about 6,300 km per hour each day an week
