Question # 2 can you show me how to solve Just a study guide so it's not graded

Analyzing Forces: Using Newton's 2nd Law A fireman has a mass of 75 kg. When the bell in the firehouse starts ringing, he slides down the pole with an acceleration of 3 m/s². What is the total force of friction acting on his body? 1. Identify the problem: What quantity are you being asked to find? What units will this answer be in? 2. Visualize and then sketch the problem. Draw arrows to illustrate the direction of the two forces acting on the fireman. Label these two forces by name. Do not use numbers yet. 3. These two forces act in opposite (+/-) directions and they will partially cancel. Assign the + value to the stronger force. The sum of these two forces is called the Net Force and it is the force which will actually move the fireman. Fill in the names of these two forces in the equation template below. (Hint: Remember that mass and weight are not the same.) Do not use numerical values yet: Net Force = + 4. Newton's 2nd Law gives us another equation for calculating Net Force: Net…

Dynamics 1. If the resultant force acting on a particle is not zero, the particle will have an acceleration proportional to the magnitudeof the resultant and in the direction of this resultant force.2. Differentiating the velocity with respect to time will obtain ____________ of the particle.3. This is simply obtained from the average velocity by choosing shorter and shorter time intervals Δt and displacementsΔt.

Projectile motion Vertical motion Projectile Uniform motion independent Free fall Gravity Trajectory 9.8 m/s² Constant speed is an object that is thrown, shot or launched upon which the is the motion of a ). It follows a curved path which is A (1). only force acting is (2). projectile. Its path is called is (4). parabolic. A projectile has two components-the vertical motion and horizontal motion. The horizontal component is (5). (3). The vertical component is (6). horizontally at (7). (8). other. Therefore, the horizontal and vertical motion can be treated separately. A projectile launched horizontally will be considered to be a free fall because there is a change only in its This means that if air resistance is neglected, a projectile moves and it falls vertically with acceleration of These two components are completely (9).…
