Block pulled with a tension at an angle: normal force, friction force, acceleration, distance.

Given a block pulled with a tension at an angle, normal force, friction force, acceleration and distance (given the time for the acceleration) are all computed.

We start by breaking the tension vector into horizontal and vertical components. Next, we analyze forces in the y-direction in order to calculate the normal force. The normal force is less than mg here because a component of the tension is pulling upward.

Next, we compute the force of friction on the block by multiplying the normal force by the coefficient of kinetic friction given in the problem. We use Newton's Second Law in the x-direction to compute the acceleration of the block, and finally we compute the sliding distance given time for the process.

Physics professor here. Good video, essence correctly explained.

Thank you so much, your video cleared my confusion about how the normal force is interpreted when dragging an object at an angle. Just one quick thing to clarify: Is this like questions where there is an object dragged or stationary on a ramp, where you have to separate the Fg vector into its components (mg*cosθ and mg*sinθ)? Many thanks in advance.

is there no tension force at the tip of the rope?
