Exercises on Newton’s Laws of Motion Problems created by: Raditya 1. A pendulum is hanging on a ceiling of a plane which is initially at rest. When the plane prepares to take off, it accelerates with a constant acceleration until its speed reaches 30 m/s. It is known that during this period, the pendulum makes an angle 45 o with respect to vertical line. Find the distance traveled by the plane until it takes off. [Answer: x = 45 . 92 m] 2. A block of mass m is at rest on a rough surface which makes an angle θ with respect to horizontal. The coefficient of static friction is μ s , but it is too small for the friction alone to be able to prevent the block from sliding down. If an external force F is to be applied to the block, as shown below, find its range of values in order to keep the block in equilibrium. 3. Look at the figure below, There is no friction between block C and the ground, but there is friction between block C and D. Also, assume that all the strings are massless and frictionless. Find the minimum coefficient of static friction between block C and D such that all the blocks move with the same acceleration. [Answer: μ s , min = ( m B + m C ) m A +( m A + m D ) m B m D ( m A + m B + m C + m D ) ] 4. Look at the figure below, 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
