An object with mass m is dragged along a horizontal plane by a force acting along a rope attached to the object as shown below mass horizontal plane If the rope makes an angle θ with the plane, then the magnitude of the force required to overcome friction is where g is the acceleration due to gravity and μ is a positive constant called the coefficient of riction, and we assume θ [0, π/2) Use the second derivative t tan...

b. Measure and record the smallest angle i. An object K and an observer at X are formed between lines C and D at E. shown below. Draw a line indicating a line of sight to an object L that lies 35° below object K on the plane of the paper as viewed by the observer at X. c. Based upon the diagram, what is the angle formed at point G between points F and H? j. Below is shown...
For this question, we are concerned with the movement of an object along a path in the plane. We are assuming that the plane is a coordinate plane and the object starts at the point. As the object moves along the path, each point on that path has two coordinates. The coordinates depend on the distance traveled along the path. Let us call this distance S, the length of the path from the origin to a point P on the...
1 If an object is on a frictionless inclined plane, how many forces act on the body? Draw a diagram indicating the forces. 2 Consider an Object on an Inclined plane at an angle of 5 degrees and also at an angle of 10 degrees. In which case will the object move faster down the incline? 3 Explain how you will calculate the acceleration of the cart from a velocity -time graph. If in the experiment, the length of the...
An object of mass 2 kg is travelling in two dimensions with constant acceleration. If its initial velocity is 12 m/s at 30 and after 15 seconds the velocity became 15 m/s at 128. (a) What is the acceleration of the object? S -2 LS (b) What is the magnitude of the force moving the object? (e) How much work was done by the force during the 15 seconds? Question 2: (5 marks) A patient of mass 75 kg is...

The pilot of a light plane heads due North at an airspeed of 240 km/h. A wind is blowing 90 km/h at an angle of 30 degrees E of N relative to the ground. A) What is the plane’s velocity with respect to the ground (give both magnitude and direction) if the pilot does not correct her course? B) In order to fly north (relative to the ground) , the pilot must fly into the wind at some angle. If...
