A) An object will accelerate if a net force acts upon it. B) For every action, there is an equal and opposite reaction. C) An object at rest will remain at rest unless acted upon by an unbalanced force. D) Force equals mass times acceleration. Astrolojide Acilar Sue Tompkins Pdf Indir Patched - 3.79.94.248

A) The table pushing up on the book. B) The book pushing down on the table. C) The Earth pulling up on the book. D) The table pushing down on the floor. B. CALCULATIONS (Show all working: Given, Formula, Calculation, Answer) 1. Kinematics: The Overtaking Car A car is moving at a constant speed of 72 km/h on a straight highway. a) Convert the speed from km/h to m/s. b) How long does it take the car to travel a distance of 900 meters ?

$F = ma \Rightarrow a = F/m = 50 / 20 = 2.5 \text{ m/s}^2$. 3. c) Acceleration would decrease because $a = F/m$. If mass doubles, acceleration halves.

A cyclist is moving at 10 m/s when they begin to brake. The bicycle comes to a complete stop after 5 seconds . a) Calculate the acceleration (deceleration) of the bicycle. b) Calculate the braking distance required for the bicycle to stop.

A) Its velocity remains constant. B) Its acceleration remains constant. C) Its acceleration increases as it falls. D) Its mass increases as it falls.

$F_g = mg = 500 \cdot 10 = 5000 \text{ N}$. 4. b) $F_{net} = F_{tension} - F_g$. $ma = F_T - F_g$. $F_T = ma + F_g = 500(2) + 5000 = 6000 \text{ N}$.

A) 200 km/h B) 50 km/h C) 50 m/s D) 102 km/h

An elevator with a mass of 500 kg is being pulled upward with an acceleration of 2 m/s² . (Assume $g = 10 \text{ m/s}^2$) a) Calculate the gravitational force (weight) acting on the elevator. b) Calculate the tension force in the cable required to lift the elevator with that acceleration. C. GRAPHICAL ANALYSIS 1. Look at the velocity-time graph below (Description provided). Imagine a line starting at $v = 0$ at $t = 0$ and rising in a straight line to $v = 20 \text{ m/s}$ at $t = 4 \text{ s}$.
