is the "momentum" of a kid.
<u>Explanation</u>:
"Momentum" of an object is defined as the "velocity" changed by an object by moving the object from "one place" to "another place". The "Momentum" of an object is represented as "". It is the product of the "mass of object" and the "velocity of object". It is mathematically written as
.
Where, "m" is mass of object and "v" is velocity of object.
Given that,
Mass of a kid is 23.3 Kg.
Velocity of a kid is 2.1 m/s.
Now, to calculate momentum of the given object us the formula .
Plug the values,
Answer:
Explanation:
<u>Motion With Constant Acceleration </u>
It's a type of motion in which the velocity of an object changes uniformly over time.
The equation that describes the change of velocities is:
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
Solving the equation for a:
The ball starts at rest (vo=0) and rolls down an inclined plane that makes it reach a speed of vf=7.5 m/s in t=3 seconds.
The acceleration is:
Answer:
Explanation:
Given,
Width of rectangular tank, b = 1 m
Length of the tank, l = 2 m
height of the tank, d = 1.5 m
Depth of gasoline on the tank, h = 1 m
The differential form with the acceleration
acceleration in z-direction = 0 m/s²
g = 9.8 m/s²
a_y is the horizontal acceleration of the gasoline.
Hence, Horizontal acceleration of the gasoline before gasoline would spill is equal to 4.9 m/s²
