Answer:
Check the explanation
Explanation:
To calculate or compute the magnitude of the velocity at whichever point in time, you’ll need to multiply the constant acceleration pace times the amount of time difference and then adding the result to the initial velocity
While To calculate or compute the horizontal component, the magnitude of the vector will just be multiplied by the cosine angle referenced to the horizontal
Kindly check the attached images below to see the full step by step explanation to the question above.
Answer:
Between 35°– 45°
Explanation:
In the vertical position, Point the flame in the direction of travel. Keep the flame tip at the correct height above the base metal. An angle of 35°–45° should be maintained between the torch tip and the base metal. This angle may be varied up or down to heat or cool the weld pool if it is too narrow or too wide
Answer:2058.992KJ
Explanation:
Given data
Mass of object
=521kg
initial velocity
=90m/s
Final velocity
=14m/s
kinetic energy of body is given by=
change in kinectic energy is given by substracting final kinetic energy from initial kinetic energy of body.
Change in kinetic energy=
Change in kinetic energy=
Change in kinetic energy=2058.992KJ
