The formula is:
Work = Force · Displacement
F = m · g
F = 16 kg · 9.8 m/s² = 156.8 N
and we know that:
d = 0.8 m
W = 156.8 N · 0.8 m = 125.44 J
Answer:
W = 125.44 J.
The end or finish of an event or process.
<u>To find the mass, with only the weight</u>:
⇒ must consider the relationship between the mass and weight
⇒ (<em>in other words</em>) we must find the equation that has both the
mass and weight
<u>Based on our physics knowledge, we know</u>:

- Weight: 147N
- Gravitational Acceleration: 9.8 m/s²
<u>Now let's plug in the values, and solve</u>:

<u>Answer: 15 kg</u>
Hope that helps!
<em>*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg</em>
Answer:
acceleration = -15.3g
Explanation:
given data
speed = 6.00 m/s.
thickness = 12
moves the entire = 12.0 cm
solution
we will use here equation that is
v² - u² = 2 × a × s ........................1
here v = 0 is the final velocity and u = 6.0 m/s is initial velocity and s= 0.12 m is the distance covered and a is the acceleration
so we put here value and get acceleration
a = 
a = 
a = -150 m/s² ( negative sign means it is a deceleration )
and
acceleration in units of g
a = 
a = -15.3 g
