A particle of mass m, initially at rest, moves on a horizontal line subject to a force F(t)=ae-bt. Show that the position and velocity of the particle as a function of time are: x = a/mb[t-1/b(1-e-bt)] and v = a/mb(1-e-bt).
A mass m is on a horizontal frictionless surface and is attached to an ideal horizontal spring of spring constant k. The equilibrium position of the free end of the spring is at x = 0. The displacement of the mass by P⃗ begins and ends with the mass at rest.the displacement begins at position xi and ends at position xf. Select all true statements.a) Wp=-Ws b)=integration(kxdx) c)Wp=0 d)Wspring=0 e)Ws= integrate(-kxdx) f)P(x)=kx
• 30 In Fig. 7-10a, a block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (spring constant k) whose other "O 0.5 1 1.5 2 end is fixed. The block is initially at x (m) rest at the position where the spring Figure 7-36 Problem 30. is unstretched (x = 0) when a con- I stant horizontal force É in the positive direction of the x axis is applied...
Problem 1 A block of mass m is sliding on a frictionless, horizontal surface, with a velocity vi . It hits an ideal spring, of spring constant k, which is attached to the wall. The spring compresses until the block momentarily stops, and then starts expanding again, so the block ultimately bounces off (see Example 5.6.2). (a) Write down an equation of motion (a function x(t)) for the block, which is valid for as long as it is in contact...
