- 1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?A 3-meter-long 25 kg beam is supported by two cables as shown below. You can treat the beam as a slender rod. Assume we want the left end of the beam at A to remain as a constant height while the right end of the beam at B to accelerate upwards at a rate of 1 m/s². a) What is the rate of acceleration of the center of the beam and the rate of angular acceleration for the beam? b) What will T₁ and T₂ need to be to achieve these accelerations?

Time a 1 hpLet us say that we have a ladder with its own length (L) and its own mass (m) this ladder just so happens to make a (θ) degree angle with a wall. The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.Q1) A car of the mass ( 100 kg ) drives with a velocity such that it has a kinetic energy of (40 k J) find the velocity if the car is raised with a crane ,how high should it be lifted in the stander gravitational filed to have a potential energy that equals the kinetic energy V=( 28,28 m /s . 30 m/s 40 m/s)H= (40 m ,30 m 20 m ) * Your answer
