andra pulls from the front while Shirley pushes a wagon with Heather riding with a net force of 50-N. The wagon has a combined mass with Heather riding of 30 kg. a) What is the acceleration of the wagon. b) If starting from rest, how much speed will the wagon pick up if they move it for 5 seconds. c) What distance does the wagon cover in 10

What happens to the object when you apply a constant force on it in space? A. It will not move B. It will continuously move C. It will move faster D. None of the above

9. On a farm, you pull a 4.3 kg bucket of water up from a well with a force of 55.2 N while a 5N frictional force acts in the opposite direction. Calculate the upward acceleration of the bucket in m/s2

A Roller Coaster train and its passengers have a combined mass of 1375 kg. The train comes over the top of the first hill on a roller coaster, 45 m above the ground with a velocity of 10.5 m/s. a) The train goes down the hill on to another hill 18 m above the ground. What is its velocity on top of the second hill. b) What will be its velocity when it reaches the ground level from the top of the second hill.

When cleaning out his impressive collection of chalkboard chalk, JohN finds a creepy looking bug hiding amongst the stack. After a split second of cye contact the bug immediately begins rushing in a straight line moving 1.5 m/s away from Jonua The startled MAN takes 3.0 seconds to locate and turn on his pocket vacuum which provides a force opposite of the bug's motion. This vacuum creates a negative acceleration of -1.0 m/s? relative to the bug's motion and remains on until the struggling bug is pulled all the way back to its original location. a. How far does the bug make it until he starts moving backwards? b. How long does it take for the bug to get sucked into the vacuum? c. With what speed does the bug enter the vacuum? Please explain indetail. Piease show what formecla is used for each papt of each question,

A baseball is thrown vertically upward with an initial velocity of 9 m/s. Neglecting air friction, what will the speed of the baseball as it goes back to its original position/height? A) 20 m/s B) 4.5 m/s C) 9 m/s D) 15 m/s

An automobile of mass 2 500 kg moving at 50.0 m/s is braked suddenly with a constant braking force of 8 500 N. How far does the car travel before stopping?a. 7.35 m b. 368 m c. 184 m d. 551 m
