## Answer to relevant Questions

A motorboat traveling on a straight course slows uniformly from 60 km/h to 40 km/h in a distance of 50 m. What is the boat’s acceleration? According to Newton’s laws of motion (which will be studied in Chapter 4), a frictionless incline should provide an acceleration of down the incline. A student with a stopwatch finds that an object, starting from rest, ...(a) Show that the area under the curve of a velocity-versus-time plot for a constant acceleration is equal to the displacement. (b) Compute the distance traveled for the motion represented by Fig. 2.23. A student drops a ball from the top of a tall building; the ball takes 2.8 s to reach the ground. (a) What was the ball’s speed just before hitting the ground? (b) What is the height of the building? In an air bag test, a car traveling at is remotely driven into a brick wall. Suppose an identical car is dropped onto a hard surface. From what height would the car have to be dropped to have the same impact as that with the ...Post your question
