Answer:
10,000kgm/s
Explanation:
Since we not told what to look for, we can as well find the momentum of the car.
momentum = mas * velocity
Given
Mass of the car = 2000kg
velocity = 5m/s
Substitute into the formula
Momentum = 2000 * 5
Momentum = 10000kgm/s
Hence the momentum of the car is 10,000kgm/s
Answer:
Minimum Area of rectangle = 24 centimeter²
Explanation:
Given:
Length of rectangle = 6 centimeter
Width of rectangle = 4 centimeter
Find:
Minimum Area of rectangle
Computation:
Minimum Area of rectangle = Length of rectangle x Width of rectangle
Minimum Area of rectangle = 6 x 4
Minimum Area of rectangle = 24 centimeter²
Answer:
-15m/s/s
Explanation:
Acceleration = change in speed/ change in time
The change in speed is calculated by subtracting the initial speed from the final speed, so the change in speed is: 50 - 80 = -30m/s. The change in time is 2 - 0 = 2.
So the car acceleration is -30/2 = -15m/s/s
It is negative because it is decelerating.
Hope this helped!
Newton's second law<span> of motion pertains to the behavior of objects for which all existing forces are not balanced. The </span>second law<span> states that the acceleration of an object is dependent upon two variables the net force acting upon the object and the mass of the object.</span>
Answer:
The average velocity for the time period beginning when t=1 and lasting 0.1 seconds = 16.40 ft/s.
Explanation:
Given that the height of the ball at time t is
The average velocity of an object is defined as the total displacement covered by the particle divided by the total time taken in covering that displacement.
If are the heights of the ball at time and , then the total displacement covered by the ball from time to is .
Thus, the average velocity of the ball for the time interval is given by
For the time interval, beginning when t = 1 second and lasting 0.1 seconds,
