Answer:
7.481W
Explanation:
power= work done÷time
power= force × uniform velocity
a= ∆v/t
29.0ms=
=(0.72-0)÷29×10^-3
a=24.83m/s^2
Newton's second law
f=ma
=(0.84×24.83)
=20.86N
w=FD
v^2=u^2+2as
0.5184=0+49.66s
s=0.0104m
20.86×0.0104
=0.216944J
0.216944÷t
P=7.481W

Answer:
Kinematics is the study of how things move while dynamics is the study of forces and motion
Explanation:
Given:
Δy = d
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2(g)(d)
v = √(2gd)
If we double d:
√(2g (2d))
√(4gd)
Compared to the first velocity:
√(4gd) / √(2gd)
√2
So the new velocity is √2 greater than the first velocity.
√2 v
Answer:
A physical trait is visible to the naked eye, such as, having six fingers; and a character trait is invisible to the naked eye, such as, being charming. Both can be subjective, for instance, claiming somebody has a big nose is a subjective comment about somebody's physical appearance.
