1.2 A force F is used to pull an object of mass M, which is suspended from a string, to one side as shown in the diagram below. The object is in equilibrium.0F1M Which ONE of the following vector diagrams CORRECTLY represents all the forces acting on the object? C BC D卡(2) ...
A block of mass m is pushed along a rough horizontal surface by a force F at an angle θ with the horizontal. The coefficient of kinetic friction between the block and the surface is μ. If the block moves a distance d, what is the work done by the net force according to the work ...
13 A constant force F is applied to a stationary object of mass m on a frictionless surface. A constant acceleration increases the velocity of the object to some value v in a time t. It covers a distance s during this time.Which value of the kinetic energy is given to the object? C...
CWhen a constan force E is applied to the stationary object and yet it accelerates constantl means that Fis in the direction of the motion Only option C gives the unit of work done, which has the same units as kinetic energy By the work energy theorem, the net work done on the object...

Step by step video & image solution for A block of the mass of 1 kg is moving on the x-axis . A force F acting on the block is shown . The velocity of the block at time t = 2 s is - 3 m s^(-1) what is the speed of the block at time t = 4 s? by Physics experts...
A block of mass m is connected to a spring (spring constant k). Initially the block is at rest and the spring is in its natural length. Now the system is released in gravitational field and a variable force F is applied on the upper end of the spring such that the downward acceleratio...
