A 30kg boy pushes a grocery cart while shopping with his mom. The cart itself has a mass of 18 and the food inside the car has a mass of 15 kg. The kinetic friction coefficient is 0.01. What is the horizontal force he needs to apply to keep the cart moving at a constant 0.75 m/s? Round your answer off to one significant figure.

    A boy shoves his stuffed toy zebra, which has mass m, down a frictionless chute, starting at a height D above the bottom of the chute and with an initial speed of V. The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with coefficient of kinetic friction mu. At what distance d from the bottom of the chute does the toy zebra come to rest? Express your answer in terms of...

    Problem 1 A roller coaster cart has a mass of 200.0kg, which includes its passengers. The cart is pushed off its beginning position by a spring with a spring constant of k 150.ON/m that has been compressed by Ax 0.50m from its equilibrium length. Friction is negligible everywhere, except for a 2-meter-long rough patch on the initial slide (see the figure below), where the coefficient of kinetic friction is uk 0.4. (For the purposes of calculation involving friction, here you...

    The Sidewinder is a shuttle type steel rollercoaster. The rollercoaster cart starts at the bottom of the frictionless track and is accelerated from a stand still over a distance of 7 meters. Then the cart enters the loop, rises to the top with just enough velocity to keep from stalling at the top of the loop. Gaining velocity the cart finishes the loop, bottoms out, and then rises up the vertical segment of the track. After stalling out at a...

    5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...

    A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

    David’s Story “Life is difficult.” I once read these three trivial words in a book, but never knew how true to life and impactful they would be until one fateful fall evening. Before I begin, let me back up and tell you more about who I am and how I got here. I am a Caucasian male raised in a small conservative town in Maine by hard-working middle-class parents. My compassionate mother juggled raising three rambunctious children, me being the...
