A 25 kilogram mass is uniformly accelerated on a horizontal smooth frictionless surface from 2 meters per second to 10 meters per second in 4 seconds.

A. So how much work is done? (energy based)

B. How much power did this require?

C. What was the momentum change?

D. If the frictionless surface is tilted to become a ramp and the mass's elevation changes by 2 meters while it was being accelerated the same amount, how much additional work was done?

E. If the above box was placed on a different ramp inclined at 15 degrees and does not slide what is the effective coefficient of static friciton?

A 5.0 kg mass is initially at rest on a horizontal frictionless surface when a horizontal force along an x axis is applied to the block. The force is given by ? ⃗(?) = (6.0?2 − 2?3)?̂, where the force in in newtons, x is in meters, and the initial position of the block is x = 0. (a) What is the work done in moving the block from x = 1.0 m to x = 3.0 m? (b) What...

a)An object of mass ?m rests on a horizontal frictionless surface. A constant horizontal force of magnitude ?F is applied to the object. This force produces an acceleration: always only if ?F is larger than the weight of the object only while the object suddenly changes from rest to motion only if ?F is increasing choice A b)Now let there be friction between the surface and the object. If the object has a mass of 10 kg, and ??μs =...

A small block on a frictionless horizontal surface has a mass of 2.95×10−2 kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1) .) The block is originally revolving at a distance of 0.295 m from the hole with an angular speed of 1.85 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.140 m ....

A mass; m1 = 64 g, sits on a frictionless horizontal surface, and is attached to a spring of spring constant k = 51 N/m. The other end of the horizontal spring is attached to a wall; the system is in equilibrium. Another mass; m2 = 18 g, strikes the stationary mass m1, and sticks to it. As a result, the spring is compressed by a distance of 24.5 cm before the masses come to a momentary stop. a) How...

A mass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. It takes 3.7 J of work to compress the spring by 0.14 m . If the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of 12 m/s2. Find the value of the spring constant. Find the value of the mass.
