Consider two boxes of masses, m and 2m, both initially at rest. You push each box separately with a force, F, over a distance, d, across a frictionless surface.  How does the final speed of the smaller box compare to the final speed of the larger box?

a. The speed of the smaller box is half that of the larger box

b. The speed of the smaller box is 4 times that of the larger box

c. The speed of the smaller box is twice that of the larger box

d. The speed of the smaller box is √​2​​​ times that of the larger box

e. The speed of the smaller box is the same as that of the larger box

    Two students are pushing identical crates across a frictionless floor. The crates are initially at rest. Bing applies a horizontal force of 19 N to his crate. Bob, who is shorter than Bing, pushes on his crate at an angle of 33° below the horizontal, also with a force of 19 N. Find the ratio of the masses of the two crates if Bing’s crate is moving at twice the speed of Bob’s crate after they have traveled a distance...

    1.A student pushes a box initially at rest, horizontally along a frictionless surface for 10.0 m and then releases the box to continue sliding. If the student pushes with a constant 15 N force, what is the box's speed when it is released? (mass not provided) 2. If the student from the previous question hadn't pushed the box horizontally, but rather, at an angle of 54 degrees relative to the frictionless surface, what would have been the box's speed when...

    A box of mass M = 0.2kg starts out at rest on a horizontal table. The surface is not frictionless. At t = 0.75s you start pushing on the box horizontally in the +x direction, causing it to speed up. The force you push with is not necessarily constant. You stop pushing on the box at t-2s, after which it slides on its own as it slows down and comes to rest at t = 4s. Between t-2s and t...

    A constant force is exerted on a cart that is initially at rest on an air track.  Friction between the cart and the track is negligible.  The force acts for a short time interval and gives the cart a certain final speed. To reach the same final speed with a force that is twice as much as the first mentioned force, the new force must be exerted on the cart for a time interval that is A. half as long as the...

    2 particles have the same net negative charge, -q but different masses, m and M.   Both particles are initially moving directly toward the right along the x-axis with the same velocity as they enter the uniform electric field. If the larger mass, M, is exactly twice the smaller mass, m (i.e, M = 2m), which of the following best describes the motion of the larger mass, M ​​​​​​​ -q Select the correct answer Mass M will be deflected upward with...

    A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After i is released the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment with a box of mass 2m A) the lighter box will go twice as high up the incline as the heavier box. B) both boxes will have the same...
