See if you can answer this problem.

When setting the price of admission tickets for the amusement park, Tabitha wants the price for a two–child, two–adult family to be $100. She also wants the adult tickets to cost $8.00 more than twice the cost of a child's ticket. How much should a child's ticket cost?

A worker pushes horizontally on a 35kg crate with a force of magnitude 110N. The coefficient of static friction between the floor and the crate is 0.37. The crate does not move at this point. Suppose that a second worker pulls directly upward on the crate to help out. What is the least vertical pull that will allow the first worker's 110N push to move the crate. At this point I have found the static frictional force and the maximum frictional force. The difference of the 2 is 16.91 N

If you were on the moon. the acceleration of gravity would be 1.6 m/s^2. if you through a ball up at 40m/s, how long would it take for the ball to reach its maximum hieght?


what would happen to the distance an object on the moon falls compared to the distance an object falls on the Earth? compare something that fell for 5 sec and 10 sec


i really need help!! plz include steps so i can try to figure out how you did it!! thanks!

A test vehicle on a track goes through photo gates spaced 25 m apart at the following times: 2.00 sec, 3.30 sec, 4.30 sec

a) Plot the position versus time of the vehicle.

b) Plot the average speed of the vehicle in the time intervals versus time.



Next Q) A rally driver has to maintain a constant speed between checkpoints. She arrives at these points at the following times

26 mi at 31 min 12 sec

48 mi at 57 min 24 sec

87 mi at 1 hr 43 min 15 sec

105 mi at 2 hr 8 min and 49 sec

a) What is the most probable (i.e. average) speed that she is trying to maintain?

b) What is her largest deviation from this average speed?



This is the hard one) What is the acceleration of a vehicle that charges its velocity from 100 km/h to a dead stop in 10 s?

Two bulbs of resistances R1 and R2 such that R1 > R2. They are connected in series. Which is brighter? What would be the case if they were connected in parallel?


~So far what I put is that in the series, the one with the least resistance would be the most brightest because it has more current flowing through it (I=V/R)

~If in parallel, I am not sure


Can you please explain to me the correct answer without using any equations. I am very confused.

A student determined to test the law of gravity for himself walks off a skyscraper 900ft tall, stopwatch in hand and starts to feefall (velocity initial equals 0 ). Five seconds later superman arrives at the scene and dives off the roof to save him.
A. what must be supermans initial velocity if he is to catch the student just before he hits the ground?
B. What must be the height of the building so that even superman can not save him? (assume supermans acceleration to be that of a free falling body)

Consider a steady flow of air through the diffuser portion of an axisymmetric wind tunnel. The air speed along the center line decreases from a value of 10 m/s at x=0 to 5 m/s at x=2 meters. The wall of the diffuser is a conical surface whose radius at the entrance is 1.0 meter.

What is an expression for the centerline speed as a function of x?

What is the acceleration along the centerline at x=1 meter?
