The Physics of Point Particles
A runner is moving at 6m/s when they begin to decelerate at 2m/s2 . How far will they travel until they come to a stop?
How do I solve this? My professor has it worked to where 6m/s is the final velocity and I don't understand why.

- When jumping, a flea accelerates at an astounding 1,000 m/s2 , but over only the very short distance of 0.5 mm. If a flea jumps straight up, and if air resistance is neglected (a rather poor approximation in this situation), how high does the flea go (write your answer in centimeters)? Acceleration due to gravity g= 9.8 m/s2.arrow_forwardCan you set up equations with variables for the two cases described? An example of a situation that I might be able to use an equation with a single unknown would be, suppose I live in a town 100 miles away from my office. How long will it take me to reach my office if I am driving at 75 mph. Time will be unknown, and I am assuming I am driving at a constant speed, so I will apply the following linear equation, Speed = Time Distance → Time = Speed Distance = 1.33hours = 1 hour 20 minutes. Now I'm in the same position as before, but now there are traffic jams, or maybe roadwork, so the speed is not constant, (it varies with time) so in this case speed(time) = time distance → time = speed(time) Distance will therefore fail in this case. In the first case, in the linear case, we can assume that the speed will be constant and independent of other variables, time, which makes the linear method useful in this situation. On the other hand, in our second example, speed is a function of…arrow_forwardWhen a ball is dropped from a state of rest at time t=0, the distance it has travelled after ? seconds is s(t)=4.9t^2 meters. a.)

- A car traveling at 60 ft/sec begins decelerating (time is zero here, as is position) at a constant 10 feet per second squared. How many feet does the car travel before coming to a complete stop? Yet another hint: is the acceleration positive or negative? Then, determine the velocity function by integrating the acceleration function, and solving for C (the fixed point will be the velocity of the car at t=0). Integrate the velocity function to determine the position function, and solve for C (the fixed point will be the position when t=0 - and I gave that info above). One more thing...to find how long it will take to stop (which you will need in order to determine how many feet it takes to stop) you will need to use the velocity function and solve for t when v(t)=0.arrow_forwardAn automobile is driven at 30 mph for 12 min, then at 40 mph for 20 min, and finally 50 mph for8min.
