Floating. When you have no gravity you have nothing to be pushing you down to the floor so that would be an example of no gravity pushing on you.
Answer:
the correct answer will be 6.82 %that is 7%
p(1.27)-q(0.83) =x=0.44
0.02+0.01 =0.03 (maximum uncertainty)
percentage uncertainty =0.03/0.44×100 %
=6.82%
=7%
Explanation: it was d on my end
Formula for acceleration: A=Force/Mass
A=F/M
A=80N/4.5kg
A=17.7 m/s^2
Unit for A is meters per second (m/s^2)
Hope this helps :)
Answer:
The spring constant is 60,000 N
The total work done on it during the compression is 3 J
Explanation:
Given;
weight of the girl, W = 600 N
compression of the spring, x = 1 cm = 0.01 m
To determine the spring constant, we apply hook's law;
F = kx
where;
F is applied force or weight on the spring
k is the spring constant
x is the compression of the spring
k = F / x
k = 600 / 0.01
k = 60,000 N
The total work done on the spring = elastic potential energy of the spring, U;
U = ¹/₂kx²
U = ¹/₂(60000)(0.01)²
U = 3 J
Thus, the total work done on it during the compression is 3 J
Explanation:
Given that,
The vertical motion of mass A is defined by the relation as :

At t = 1 s

x = 115.33 mm
(a) We know that,
Velocity, 


At t = 1 s

v = 18.94 mm/s
We know that,
Acceleration, 


At t = 1 s


(b) For maximum velocity,

t = 45 seconds
For maximum acceleration,

t = 61.8 seconds
Hence, this is the required solution.
