Answer:
it is important to create measurable goals bc :
- To determine the point at which the goal has been achieved.
- It can also help improve motivation allowing an individual to track the progress towards the goal.
hope it helps!
The correct answer is true
Answer:
to go 20 m/s means that the body travels 20 metres of distance in each second.
Hope it will help :)
Answer:
0.6 m
Explanation:
When a spring is compressed it stores potential energy. This energy is:
Ep = 1/2 * k * x^2
Being x the distance it compressed/stretched.
When the spring bounces the ice cube back it will transfer that energy to the cube, it will raise up the slope, reaching a high point where it will have a speed of zero and a potential energy equal to what the spring gave it.
The potential energy of the ice cube is:
Ep = m * g * h
This is vertical height and is related to the distance up the slope by:
sin(a) = h/d
h = sin(a) * d
Replacing:
Ep = m * g * sin(a) * d
Equating both potential energies:
1/2 * k * x^2 = m * g * sin(a) * d
d = (1/2 * k * x^2) / (m * g * sin(a))
d= (1/2 * 25 * 0.1^2) / (0.05 * 9.81 * sin(25)) = 0.6 m
height = .0970 mm = .00831 inches
Volume = length * breadth * height = 8.5 * 11 * 0.00381
Volume = 0.776985 inches^cube
