At t=0 a body of unit mass initially at rest at the origin begins to move along the x-axis under
the influence of a force ? = 1/√(1 +
?^3), Find the velocity of the body at intervals of 0.2 from t=0
to t=2. Use Simpson Rule (1/3).
Note: Newton second law, F = m . a , where F: force , m: mass and a : acceleration

Question: A block of mass m is at rest at the origin at t=0. It is pushed with constant force F0 from x = 0 to x = L across a horizontal surface whose coefficient of kinetic friction is ?k = ?0 ( 1 ? x / L ). That is, the coefficient of friction decreases from ?0 at x = 0 to zero at x = L. Part A: We would like to know the velocity of the block...

A block of ice with mass 6.00 kg is initially at rest on a frictionless, horizontal surface. A worker then applies a horizontal force F⃗ to it. As a result, the block moves along the x-axis such that its position as a function of time is given by x(t)=αt2+βt3, where α = 0.210 m/s2 and β = 2.07×10−2 m/s3 .Calculate the velocity of the object at time t = 3.50 s .Calculate the magnitude of F⃗ at time t =...

A model of rocket weighing 0.2 lbs is initially at rest at time t = 0 when launched vertically upwards using a propulsive force of 2 lbs. This propulsive force is applied from 0 <t ≤ 1 sec. When t> 1 sec, the propulsive force stops acting. By neglecting the resistance of the air and assuming that the mass of the rocket remains constant, determine a) The time required for the rocket to reach its maximum height. b) The maximum...

As shown in Figure 1, a block (mass: 2.4 kg) is initially at rest near the top of an inclined plane, oriented at a 25° angle above the horizontal. The coefficients of static and kinetic friction along the incline are 0.2 and 0.1, respectively. (a) Just after the block is released from rest, draw a free-body diagram for it. (Assume that the block is moving after being released from rest.) (b) Determine the magnitude of the normal force acting on...
