A block moving on a horizontal surface is at xx = 0 when tt = 0 and is sliding east with a speed of 12.0 m/sm/s.

A customer sits in an amusement park ride in which the compartment is to be pulled downward in the negative direction of a y axis with an acceleration magnitude of 1.52 g, with g = 9.80 m/s2.

Freefall is the motion that an object undergoes when the only force acting on the object is the force of gravity. Typically the vertical direction is labelled by the y coordinate and the constant acceleration equations of motion are simply modified (i.e. just replace a with y). v = vo + at y – Yo = vot + ať? y – Yo = } (vo + v) t v? = v3 + 2a (y – yo) Which of the following statements about freefall motion are correct? If an object in freefall has an downwards velocity of 10 m/s then the acceleration of gravity in the constant acceleration equations of motion is a = -g = -9.8 m/s². If an object in freefall has an upwards velocity of 10 m/s then the acceleration of gravity in the constant acceleration equations of motion is a = -g = -9.8 m/s². If the Y-coordinate system is chosen to point upwards (i.e. Y increases when moving up), then the acceleration of gravity in the constant acceleration equations of motion is a = -g= -9.8 m/s². For an object to be in freefall then it must be…

An object undergoes one-dimensional motion along the x-axis subject to the the decelerating force dv kæv² m dt At time t = 0, the object's position is x = 0 and its velocity is v = v0. The decelerating force is a dv dv dx function of the object's position x(t) and velocity v(t). Using the fact that dt transform the dx dt problem into one having x as the independent variable. Solve for v as a function of x and v0 then determine the position xf at which the object comes to rest. If the object does not come to rest then xf = 00 (enter oo for infinity) dv = V = Xf = Question Help: O Message instructor Submit Question

A speedboat is cruising at a speed of 11.8 m/s in still water when it shuts off its engines and coasts to rest. The water exerts drag forces on the speedboat such that its speed during coasting is given by v = v₁e-ct, where v is the speed at time t, v, is the initial speed at t = 0, and c is a constant.

While watching the Minty Mania Grand Prix (the first race of the Marbula One 2020 season), you're curious about a few things. You notice that the marbles move downhill during the entire race (the slope of the track changes at different points), and then are lifted back to the starting line by a conveyor belt at the end of each lap. The announcer mentions that the conveyor belt lifts the marbles a height of 40.0 cm, at a constant speed of 0.095m/s, and that the length of the conveyor belt is 52 cm. He also mentions that the length of the track (from start line to finish line) is 10.26 m. You can assume that the marble is already moving at this speed when it starts moving up the conveyor belt. You also know that the mass of each racer (marble) is 6.6 g. To simplify the analysis, you decide to model the force of friction acting on the marble (due to interactions with the track, walls, and other marbles) as a constant 0.002 N force. To satisfy your curiosity, determine the power of the…
A car weighing 2.5 metric tons and traveling at 90 km/h hits a 500 m long stretch of black ice. Unfortunately, due to skidding, neither accelerating nor braking has any effect on the speed! The driver manages to maintain steady straight direction of motion and the only impact is provided by the ice friction force, which is numerically equal to 4v² Newtons, where the velocity v of the car is measured in m/sec. (a) Using Newton's Second Law F = ma, set up a mathematical model for the position x(t) and velocity v(t) of the car as functions of time t. Start by drawing a diagram and choosing a consistent system of units based on kg, m, sec (1 ton = 1000 kg, 1 m/sec = 3.6 km/h, 1 N = 1 kg · m/sec²). Introduce and label the variables, show the units and write down the differential equations and the intial conditions. (b) Use the model in part a to calculate v(t) and x(t). Fully show the process of solving the initial value problems. (c) Based on your work so far, how long will it take to pass…
