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.) }
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?
A 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+).
W₁ = fd
Wf work done by friction
f = force
d = distance
Question:
How much work done by friction was exerted on the car as it moved down the inclined plane?
You may use a calculator.
