Answer:
Based on what we have learned so far, in what ways have the experiences of Asian-Canadians stayed the same over time? Why do you think these similarities exist? Please give specific examples to support your ideas.
Explanation:
Answer:
12 m/s
Explanation:
First, find the time it takes for the ball to fall 2.0 m.
y = y₀ + v₀ t + ½ at²
0 = 2.0 + (0) t + ½ (-9.8) t²
0 = 2 − 4.9t²
t = 0.639
Find the velocity needed to travel 7.8 m in that time.
x = x₀ + v₀ t + ½ at²
7.8 = 0 + v₀ (0.639) + ½ (0) (0.639)²
7.8 = 0.639 v₀
v₀ = 12.2
Rounded to two significant figures, the initial velocity is 12 m/s.
Answer:
Explanation:
The condition for translation equilibrium is that is that the net force acting on the body must be zero.
The sum all the external forces acting on the body in horizontal as well as vertical direction must be zero.
∑Fₓ=0 and ∑Fy=0
now if the above two condition are satisfied the rigid body is said to be in translational equilibrium.
God bless... hope this help to clear your doubt.
<span>We know that the work formula is calculated as force by distance:
W = F * d
W = 5 * 3 = 15 N*m = 15 Joules
So the work done on the object is 15 joules</span>
