In addition, include an additional vector denoting the direction of acceleration. (a) An elevator, suspended by a cable, is speeding up as it descends towards the ground. (b) A rocket is moving at constant speed upwards. Do not ignore air resistance. (c) A box is sitting in the back of a moving truck when the truck slams on its brakes. The box does not move in the bed of the truck. (d) A soccer ball being kicked by you. Your foot and the ground are still in contact with the ball. (e) The soccer ball of the previous part is now in the air, do not ignore air resistance.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Problem 1: A book is resting on a frictionless table until someone suddenly starts applying a constant force on it right until it reaches the end of the table. The book was constantly accelerating until it reached the end of the table. First, write down your thinking process as in the previous example, and then draw in the space provided below the book's motion diagram along with the velocity, acceleration, and force vectors. Draw book's motion diagram with velocity, acceleration, and force vectors. (Hint: Since the motion is horizontal, draw a horizontal motion diagram.)

please help me. double and triple check your answers, previous tutors got it wrong. this is a practice problem, not for a grade. i attached the question in one screenshot, and my previous incorrect answers as another. this is part c so what i got outta part A and B is the minimum value of the coefficent is 0.49 and the answer to part b which asked, As the snow begins to melt the coefficient of static friction decreases and the snow finally slips. Assuming that the distance from the chunk to the edge of the roof is 6.0 mm and the coefficient of kinetic friction is 0.17, calculate the speed of the snow chunk when it slides off the roof, is 5.8 m/s
Task 1: Vector components and free body diagrams Two essential concepts you were learning in the course up to this point were determining the components of a vector and drawing a free body diagram that represents the forces acting on an object. 1. For each of the following, determine the components that make up the resultant vector. a. F = 40 N 25° V-25N 15 E S 15% =25 m/s c. A person throws a ball with an initial velocity of 17 m/s, 65° above the horizontal. -17 m/s 65° X 2. For each of the following draw a free body diagram that includes all of the forces acting on the object described. a. A 40 kg box on a level floor is pulled by a rope attached to the box. The ropes makes an angle of 21° with the horizontal. A force of friction opposes the motion. b. A refrigerator sits on a level floor and a person tries to push on it with a force parallel to the floor. The refrigerator does not move.
