Answer:
I think you are looking for the velocity, so the answer is 38.5 m/s
Explanation:
Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.
Answer:

Explanation:
Given,
For the first rocket,
- Initial velocity of the first rocket A =

- Acceleration of the first rocket =

For the second rocket,
- Initial velocity of the second rocket B =

- Displacement of both the rockets A and B = s = 0 m
Fro the first rocket,
Let 't' be the time taken by the first rocket A for whole the displacement

Let
be the acceleration of the second rocket B for the same time interval
from the kinematics,


Hence the acceleration of the second rocket B is -33.65\ m/s^2.
Answer:
P = 1401.4 x 10⁶ W
Explanation:
Given that
Water flow rate m = 2.2 x 10⁶ kg/s
Height ,h= 65 m
Acceleration due to gravity ,g= 9.8 m/s²
The power P is given as
P= m g h
P=Power
m=Water flow rate
h=height
Now by putting the values in the above equation
P = 2.2 x 10⁶ x 9.8 x 65 W
P = 1401.4 x 10⁶ W
Therefore the power wasted will be 1401.4 x 10⁶ W.
Answer:
Height, h = 10.20 meters
Explanation:
It is given that,
Mass of the object, m = 3 kg
Energy of object, E = 300 J
Let it will moved to a height of h. The energy possessed by it is called gravitational potential energy. It is given by :



h = 10.20 meters
So, the object will move to height of 10.20 meters. Hence, this is the required solution.
The force of the object with the given mass and acceleration is determined as 10 N.
<h3>
Force of the object</h3>
The force of the given object is calculated from Newton's second law of motion as follows;
F = ma
where;
- m is mass of the object = 5 kg
- a is acceleration of the object = 2 m/s²
F = 5 x 2 = 10 N
Thus, the force of the object with the given mass and acceleration is determined as 10 N.
The complete question is below:
Rearranging the equation m = F/a and solve for F, m= 5Kg and a= 2 m\s2
