Individual's Saving Accounts
According to an article by CNBC, a new survey finds the median American household has $2,729 in a savings account in 2019 and 34% of Americans have nothing saved. What does this say about Americans financial management? How does the lack of saving impact other Americans?
Each month, a Filipino household generates an average of 30 pounds of garbage for recycling. Assume that the distribution is normal with a standard deviation of 2 pounds. If a household is selected at random, find the probability of its generating more than 34 pounds per month.Β *
You are standing on the sci.com. building 46.0 m high above the ground. Your classmate, 1.8 m tall, is walking alongside the building at a constant speed of 1.20 m/s. If you wish to drop an egg onto his head,
a) where should he be when you release the egg? Assume that the egg is in free fall.
b) what will be the velocity of the egg when it hits his head?

A car heading east through a city accelerates after passing a signpost marking the city limits. It is accelerating at
constant magnitude of 3.0 m/s2. At time t = 0 the car is 5.0 m east of the signpost, moving east at 15 m/s. a) Find the carβs position at t=2.0 s.
b) Find the carβs velocity at t=2.0 s.
c) Where is the car when its velocity is 25 m/s.
If a student jumps straight up to a height of 0.440m, what is his initial speed as it leaves the ground? How long
is he in the air?
A car is stopped at the traffic light. It then travels along a straight road so that its distance from the light is given by π₯(π‘) = ππ‘2 β ππ‘3 where b=2.40 m/s2 and c=0.120 m/s3.
a) Calculate the average velocity of the car for the time interval t=0 to t=10.0 s.
b) Calculate the instantaneous velocity of the car at t=0 and t=10.0s
c) How long after starting again from rest is the car again at rest.
