In order to be able to compare the direction and strength of forces being applied to objects, it would be useful if our force diagrams gave us some information about how strong the forces acting on an object are and in which direction they act. As shown on the previous page, a gentle shove to the right could be represented by this force diagram: Force exerted on cart by hand Now suppose you gave the same cart a harder push back along the track in the opposite direction. Which of the force diagrams below do you think conveys the information that the second push was both harder than before and in the opposite direction? Force exerted on Force exerted on Force exerted on cart by hand cart by hand cart by hand A B

Newton’s 2nd Law stipulates that “the sum of all forces acting on an object are equal to the mass times the acceleration of that object.” Given the force diagram below, calculate the acceleration of the object (both magnitude and direction). The object is the smiley face, which weighs 12.6 kg (it’s a very heavy smiley face)
Three blocks are stacked on top of each other inside an elevator as shown in (Figure 1). Answer the following questions with reference to the eight forces defined as follows. • the force of the 3 kg block on the 2 kg block, F3 on 2, • the force of the 2 kg block on the 3 kg block, F2 on 3. • the force of the 3 kg block on the 1 kg block, F3 on 1. • the force of the 1 kg block on the 3 kg block, F1 on 3, • the force of the 2 kg block on the 1 kg block, F2 on 1. • the force of the 1 kg block on the 2 kg block, F1 on 2. • the force of the 1 kg block on the floor, F1 on floor, and • the force of the floor on the 1 kg block, Ffloor on 1.

Three identical blocks of massm on a frictionless surface are connected by massless taut strings. A force Fis applied on the rightmost block as shown in the figure below so that each block moves to right with acceleration a. F m m Applying Newton's second law on the rightmost block: EFx = = ma Applying Newton's second law on the block at the center: EFx = - T2 = Applying Newton's second law on the leftmost block: EFx = = ma If each block has a mass of 10 kg and is accelerating at 2 m/s2, the magnitude of the tension on the second string is T2 = N.
Student 1 has the following graph. Estimate what the graph for student 2 would look like if they increased the mass of car. Would acceleration decrease? Please draw how the line for student 2 would look like.

The data below is from a student who walked slowly up the stairs, walked quickly up the stairs, and ran up the stairs. Table 1 Mass of Student 55 kg Height of Stairs 2.8 m Force due to Gravity Calculations 1 Calculate the force due to gravity acting on the student. (Reminder: F = m*a; acceleration due to gravity = 9.8 m/s/s). Show your work below and record the value you get in Data Table 1.
Can you help me with this 2 questions 5 minutes left. this is also my last question thank youuu Which of the statements is false? forces may be classified as concentrated or distributed we can classify the effect of a force on a body as either external or internal The principle of transmissibility states that a force may be applied at any point on its line of action without altering its effect on a body acted upon by it none of the above What refers to a pair of equal, opposite, and parallel forces? torque moment couple / all of the above.
Use the picture below of a cart on an inclined ramp to answer the following question: Raising the height of the ramp, h, compared to its current position will Ih cause the cart to accelerate more quickly have no effect on the acceleration of the cart increase the value of g. cause a greater final velocity for the cart when it reaches the end of the ramp both a and d
Remember to keep 3 digits in your answers below.A shopper at the local grocery store exerts a net force of 9.8 N on a 4-kg shopping cart for 3.3 seconds.(a) According to Newton's 2nd Law, Σ F = ma, what is the acceleration of the shopping cart?a = ______ m/s2 (b) We learned in our discussion of motion that the acceleration of an object measures how the speed changes with respect to time, a = vf - vi t Using the acceleration found in part (a), the time given, and the fact that the cart starts from rest (vi = 0 m/s), determine the final speed of the shopping cart. Hint: In the expression for acceleration above, if you multiply both sides of the equation by the time, you can solve for vf. More specifically, a t = vf - vivf = ______ m/s.
Chapter 2: Newton's Laws of Motion Newton's 2nd Law Bronço Brown skydives and parachutes from a stationary helicopter. Various stages of fal! are shown in positions a through f. Using Newton's 2nd law, Fnet W - R a = find his acceleration at each posițion (mark your answers in the blanks to the right). You need to know that Bronco's mass m is 100 kg so his weight is a constant 100 0 N. Air resistance Rvaries with speed and cros- sectional area as shown.
