Machine does work with one motion true. for example wind fan
Answer:
Speed of the car, v = 8.90 m/s
Explanation:
It is given that,
The centripetal acceleration experienced by the car,
Diameter of the circle, d = 27 m
Radius of the circle, r = 13.5 m
The centripetal acceleration is experienced by an object if it moves in a circular path. The formula for the centripetal acceleration is given by :
v = 8.90 m/s
So, the maximum speed of the car in this roundabout is 8.9 m/s. Hence, this is the required solution.
Answer:
m/s
Explanation:
Given
Required
Determine Jupiter's velocity
First, we calculate the circumference (C) of Jupiter:
Substitute values for r and
Next, convert time to seconds:
The velocity is then calculated as:
m/s
<em>Hence, Jupiter's velocity is 1306.76m/s</em>
Answer:
friction coefficient on the rough road is 0.117
Explanation:
As we know that car is taking turn on flat rough road
So here we can say that required centripetal force for circular motion of car is due to frictional force
So we have
now we have
so we have
Answer:
accelerated motion
Explanation:
a change in velocity (10 m/s to 50 m/s) over time (5 s) is called acceleration.
40/5 = 8 m/s²
