One simple model for a person running the 100 m dash is
to assume the sprinter funs with constant acceleration until
reaching top speed, then maintains that speed through the
finish line
If a sprinter reaches his top speed of 108 m/s in 2.84 N. what will be his total time?

This rule has made it possible to avoid many accidents. a. If a car travels at 60 km / h, what distance (in meters) will it travel in 3 seconds? Assuming there is an accident 20 m from where you are, what acceleration must you have to bring the car to a complete stop before reaching the accident?b. Repeat part a considering a speed of 90 km / hc. Repeat part a considering a speed of 120 km / hd. Repeat part a considering a speed of 150 km / harrow_forward
- One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.arrow_forwardA ball is dropped from an initial height of 25.0 m off of a cliff. A. Consider the following quantities (1) the speed of the ball (2) the velocity of the ball (3) the acceleration of the ball.
