When Galileo Galilei rolled a ball down an inclined plane, it traveled 1.0 meters in the first second, and a total of 4.0 meters in the first two seconds. What was its acceleration on this inclined plane?
2.0 meters per second2
3.0 meters per second2
4.0 meters per second2
5.0 meters per second2
6.0 meters per second2
Rotate the ball horizontally on an 80 cm long non-stretchable cord with angular
velocity of 3 s^(-1). After ten seconds of clockwise rotation, the cord breaks. At what
speed and in what direction does the ball fly, if it was faced north at time t = Os?
Where and after how much time does the ball land on the ground that is 1 m below
the plaine in which we rotate the string? {Solution: v= (0.37 m/s,2.37 m/s); d=1.07 m,
t=0.447 s.) }
When Galileo Galilei pushed a ball down an inclined plane, it had an initial velocity (vo) of 4.0 meters per second (time = 0 seconds) and a final velocity (vf) of 10.0 meters per second (time = 2 seconds). How far did the ball travel along the inclined plane in these 2 seconds?
14 meters
20 meters
28 meters
40 meters
84 meters

- a toy car rolls 10 meters (m) across the floor. it takes 5 seconds (s) to cross this distance. what is the speed of this car?arrow_forwardA scientist was investigating if differences in the frictional work performed on a model car can change depending on its mass (in grams) and whether the car moves up or down an inclined plane. They decided to measure the amount of frictional force experienced by the model car and the distance it traveled in meters. The scientists were able to evaluate the frictional work using the following data. Mass (g) Distance (m) Force Work Done by Friction (J) car going up the incline 100 39 0.063 2.457 car going down the incline 70 39 0.2309 ? It is known that the relationship between force and distance determines the work done by friction (W+).
