a 250 kg cart is initially at rest on a horizontal frictionless surface. you push the cart with a constant horizontal force to the right making it move 12 m to the right. in the end, you did 1400 j of work on the cart. What is the magnitude of your force on the cart?
• 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...
An object, which is initially at rest on a frictionless horizontal surface, is acted upon by four constant forces. F is 21.6 N acting due east, F2 is 28.6 N acting due north, F3 is 43.5 N acting due west, and Fl is 10.8 N acting due south. How much total work is done on the object in 2.22 s, if it has a mass of 22.0 kg? total work done on object: Which type of energy is changing for...
A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 540 N / m. The block is pulled from its equilibrium position at x=0.000 m to a displacement x=+0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the block's position is x=0.057 m, its kinetic energy is closest toA. 1.0 J.B. 0.85 JC. 0.80 JD. 0.95 J.E. 1.1 J.
