QUESTION 28 You push a 80-kg file cabinet to the right on a frictionless horizontal surface with a force of 175 N from rest, the cabinet moves a distance of 12 m. What is the final speed of the cabinet, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A force of F=x^2 in Newtons acts on an object of mass m= 2 kg. If the object is at rest at x= 0 when the force F begins to act on it, what is the object’s speed at the position x= 3 m? A) 3 m/s B) 6 m/s C) 9 m/s D) 27 m/s
Vmax In a laboratory experiment, a sphere of diameter 8.0 mm is released from rest at t = 0 at the surface of honey in a jar, and the sphere's downward speed v when it travels in the honey is found to be given by v = Vmax (1 - e-t/T), where 0.040 m/s and T = 0.50 s. (a) Obtain an expression for a(t). (b) Draw graphs for v(t) and a(t) for the time interval 0 to 2.0 s. (c) Obtain an expression for x(t), choosing the positive x axis as downward, and draw the graph for this func- tion. (d) Use your x(t) graph to determine the time interval needed for the sphere to reach the bottom of the container if the surface of the honey is 0.10 m above the bottom of the jar. ... =
A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?
An Atwood’s machine is set up by suspending two blocks connected by a string of negligible mass over a pulley, as shown above. The blocks are initially held at rest and then released at time t0=0 s. The speed of the 3 kg block at time t1=2.0 s is most nearly: A) 2.0 m/s B) 4.0 m/s C) 7.0 m/s D) 10.0 m/s
40 m- 11. The roller-coaster car shown passes a vertical height of 25 m on the second hill. Determine the velocity of the car, whose mass is 800. kg, at point 2 if it starts moving at 10.0 m/s at point 1 on a frictionless track. y=0 -25m-->
