Question 3 Terminal velocity can be described as the maximum speed an object can travel falling to the amount matter contained in an object. an unbalanced force acting on the object. the amount of inertia th

6 )  Many people buy a coffee or other hot beverage on their way to work. For safety, the cup usually has a lid and is placed in a cup holder. Using Newton’s first law, explain why both of these precautions are necessary.

2. A canon ball of 5 kg is fired upward with initial speed of 56.25 m/s, it reach its highest point after 4.5s. (i) Find the acceleration of the canon ball. (ii) Find the net force acting the canon ball. (iii) Compare the net force with gravitational force, and justify your result. (iv) Draw the free body diagram. 3. The cable hanging a 1800 kg elevator has a maximum strength of 20000 N. (i) Draw the free body diagram. (ii) Find the maximum acceleration of the lift before breaking of the cable.

4) A 0.500 kg object is suspended from the ceiling of an accelerating boxcar as seen in Figure. If a= 3 m/s², find a) The angle that the string makes with the vertical b)The tension in the string

1. A 92-kg water skier floating in a lake is pulled from rest to aspeed of 12 m/s in a distance of 25 m. What is the net forceexerted on the skier, assuming his acceleration is constant? Graph and Explain.

1.) A 100-lb block slides down a frictionless inclined plane at an angle of 60° with the horizontal. Determine the accelerating force, the required to travel the first 20ft and the time required travel the next 20ft. 2.) A 100-lb is attached to a rope and is pulled upward with a force of 1501lb. What is the upward acceleration of the body? 3.) A 12-kg block is acted upon by two forces that in opposite direction, one a 540N and the other of 1260N. Determine the acceleration produced. How is the direction of the acceleration related to the forces? 4.) 3.5-kg block rest on a horizontal tabletop. A cord is attached to this block, the cord passing over pulley at the edge of the table. At the end of the cord is hung another block weighing 5N. Determine the tension in the cord and the distance the blocks move after 2 seconds.

True or False, write T if the statement is true and write F if the statement is False. This is all about General Physics 1: Newton's Laws of Motion.

2. Two blocks of masses ml and m2, with ml has greater mass than m2, are placed in contact with each other on a frictionless, horizontal surface as shown in the figure. A constant horizontal force is applied to ml as shown. Find the magnitude of the acceleration of the system. L.- (b) *Previous Next

2. An incline of the dimensions shown rests on the ground. Two boxes of equal mass are attached by a rope of negligible mass strung around a pulley at the top of the incline. The coefficient of static friction for 5 m the box on the incline is 0.6 and the coefficient of kinetic friction for the box on the incline is 0.5 10 m A) If it starts from rest at the top of the incline, how long does it take the box hanging in the air to reach the ground? B) What velocity does it have halfway to the bottom?
