sports car with a mass of 1,385 kg is at rest on a flat, horizontal road. 5.4 s later, that car is moving forward at a speed of 90 mph. Calculate the acceleration of the car and the average net force acting on the car. For this problem: Draw a diagram of the motion Draw a free body diagram. Write your N2 Law equation List your kinematics variables Solve the algebraic equation using variables.

Problem 4: A crate sits on a rough surface. Using a rope, a man applies a force to the crate, as shown in the figure. The force is not enough to move the crate, however, and it remains stationary. Use f to represent the force of friction. Please use the interactive area below to draw the Free Body Diagram for the crate. L. y 1 Add Force S Reset All Ftotal,x: Ftotal.y:

How do I solve 1a, 1b, 1c

I need hand written solution only

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.)

Cars now have steering columns and front bumpers that collapse upon impact in a front end collision. Using the kinematics of ACCELERATION and F=MA explain why that REDUCES the forces on a person in the car in a front end collision.   2. Give THREE examples of FORCES in your future career (in MD, DO, DDS, PA, PT, Envir. Sci, etc.) AND the physical mechanisms that produce those forces (such as muscles powered by ATP and explain how the ATP produces those forces, or the forces on the walls of blood vessels exerted by systolic and diastolic blood pressure.)   (Pls help me answer those two parts in the minimum word caunt of 200 words Pls I reallt need help with this!!)

Please answer.

You don't need to make a free body diagram

The tire on this drag racer is severely twisted: The force of the road on the tire is quite large (most likely several times the weight of the car) and is directed forward as shown. Is the car speeding up or slowing down? Explain.

Two blocks , each of mass m = 4.0 kg, are hung from the ceiling of an elevator as shown below.  The elevator moves with an upward acceleration a, and the tension of the rope supporting the upper mass is  T1 = 80N. Find: Provide free body diagrams and summation of the forces. 1. The magnitude of the acceleration. 2. The value of Tension T2
