Answer:
To find the distance traveled by the bicyclist during the given time, we can use the formula:
Distance = (Initial Velocity * Time) + (0.5 * Acceleration * Time^2)
Since the bicyclist starts from rest, the initial velocity is 0 m/s.
Given:
Initial velocity (u) = 0 m/s
Final velocity (v) = 11.0 m/s
Time (t) = 3.40 s
Using the formula, we can calculate the distance traveled:
Distance = (0 * 3.40) + (0.5 * Acceleration * 3.40^2)
To find the acceleration, we can use the equation:
Acceleration = (Final Velocity - Initial Velocity) / Time
Acceleration = (11.0 - 0) / 3.40
Acceleration = 11.0 / 3.40
Now, we substitute the value of acceleration into the distance formula:
Distance = (0 * 3.40) + (0.5 * (11.0 / 3.40) * 3.40^2)
Simplifying further:
Distance = 0 + (0.5 * (11.0 / 3.40) * 11.56)
Distance = (0.5 * (11.0 / 3.40) * 11.56)
Distance = (0.5 * 11.0 * 3.40)
Distance = 0.5 * 37.4
Distance = 18.7 meters
Therefore, the bicyclist traveled a distance of 18.7 meters during the given time of 3.40 seconds.
Answer:
Kinetic Energy = 1/2 mass*velocity^2
K=1/2mv^2
Therefore if you reduce the speed of an object by 1/2, K reduced to 1/4 its value.

A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.
The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.
Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.
Assuming the printer consumes electrical energy at a steady rate, then:
100 ÷ 60 = 1.6667 watts per minute.
Now, calculate the power consumed in 30 seconds,
1.6667 ÷ 2 = 0.8333 watts.
Therefore, the power consumed in 30 seconds will be 0.8333 watts.
