Three cars (car F, car G, and car H) are moving with the same velocity when the driver suddenly slams on the brakes, locking the
wheels. The most massive car is car F, the least massive is car H, and all three cars have identical tires. (a) Which car travels the longest distance to skid to a stop? A) Car F B) Car G C) Car H D) They all travel the same distance in stopping. (b) For which car does friction do the largest amount of work in stopping the car? A) Car F B) Car G C) Car H D) The amount of work done by friction is the same for all cars.
Because a massive car will have more inertia which will make the car move faster but a massive car simultaneously will have more friction thereby restricting its movement in the forward direction. Hence, all the three cars will move equal distance.
b) Option A, Car F
Being most massive car, the frictional force required to stop the car will be highest.
planning charts used to schedule resources and allocate time is the correct answer
Explanation:
Gantt Charts are a project planning tool used to track the projects from the start to endpoint.
Gantt charts are used for the preparation and planning of the projects.
By using Gantt charts we can assess how much time a project would take to complete and we can also determine resources required with the help of Gantt charts.
