A car traveling at 40km/h has it's speed reduced to 10km/h in 2.0s. Assuming that the same deceleration would be in effect, find how far the car will travel in coming to rest from a speed of 60km/h?
I'm thinking about calculating the acceleration using the givens from the first part, to calculate the second part.hage567 said:What are you thoughts on how to start this problem?
Okay, so after converting all the units to m/s..hage567 said:That's the right approach, but that equation is not quite right. That t should be a d (as in distance). Check for another equation.
You will need to convert your quantities so they are all in the same units. I usually work in meters and seconds in these questions. I would start with that before you do anything else.
Equations of motion are mathematical formulas used to describe the motion of an object in a certain system. They take into account factors such as position, velocity, acceleration, and time to determine the movement of an object.
Equations of motion are used in various fields of science, including physics, engineering, and astronomy. They help us understand and predict the behavior of objects and their motion in different systems.
The three basic equations of motion are:
1. Velocity equation: v = u + at
2. Displacement equation: s = ut + 1/2at²
3. Acceleration equation: v² = u² + 2as
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
s = displacement
Yes, equations of motion can be applied to both linear and circular motion. However, for circular motion, additional equations such as centripetal acceleration and centripetal force are also needed to fully describe the motion.
Equations of motion are based on certain assumptions and may not accurately describe the motion of objects in all situations. They do not take into account factors such as air resistance, friction, and other external forces that may affect the motion of an object. Therefore, they may have limitations in real-life scenarios.
