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 it was released?

Answer #1

dot th in KE as the boxii 它。 = (7:32 -velocity is always dependent on the mass of the object in these problems

Plz comment in case any doubt or plz rate

    025 (part 1 of 4) 10.0 points A man pushes a 24 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually in- creases his force so that the force he exerts on the box varies in time as F (7.7 N/s) t. Af- ter 4 s, he stops pushing the box. The force is always exerted in the same direction. What is the velocity of the box after...

  • Block A of mass mA is moving horizontally with speed Va along a frictionless surface

     Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...
