A car slows down from +32 m/s to +8 m/s in 4s. Calculate the acceleration .
a = change in velocity / change in time
a = 8 - 32 / 4
a = -6m/s^2
Carl puts the pedal to the metal and increases her speed as follows: 0 mi/hr at 0 seconds; 10 mi/hr at 1 second; 20 mi/hr at 2 seconds; 30 mi/hr at 3 seconds; and 40 mi/hr at 4 seconds. What is the acceleration of Car;'s car?
Friction force acting on the box if a horizontal force is applied with a magnitude of 0 N
What is the term used to describe a force that equals the sum of two or more forces?
a soccer ball is kicked with a velocity of 8m/s at angle of 23°. what is the ball's acceleration in the vertical directions as it flies through the air
