Net force is calculated using the equation
F=ma
where m is mass and a is acceleration.
So, F=(1600kg)(4.5m/s^2)
= 7200N
Answer:
The first option, energy is transferred.
Explanation:
Answer:
50 Kg.
Explanation:
The following data were obtained from the question:
Force (F) exerted = 1000 N
Acceleration (a) = 20 m/s²
Mass (m) of object =?
Force (F) is simply defined as the product of mass (m) and acceleration (a). Mathematically, it is expressed as:
Force (F) = mass (m) × acceleration (a)
F = ma
With the above formula, we can obtain the mass of the object as illustrated below:
Force (F) exerted = 1000 N
Acceleration (a) = 20 m/s²
Mass (m) of object =?
F = ma
1000 = m × 20
Divide both side by 20
m = 1000/20
m = 50 Kg
Thus, the mass of the object is 50 Kg
Answer:
In physics a null is a point in a field where the field quantity is zero as the result of two or more opposing quantities completely cancelling each other
Answer:
1.32 m
Explanation:
from the given figure we can find the velocity at the hole in the container
let it be v and we know that
then 
h= 15-4= 11 cm , g=9.81
v=14.69 m/s
now using
s=ut+0.5at^2
t= is the time required by water to reach bottom of the container
u = velocity in vertical direction is zero.
therefore,
t= 0.09030 sec
let x be the distance far from the container will the water land
x=vt
x=14.69×0.09030 = 1.32 m
