Answer:
55,42 J
Explanation:
Since the height of the room is 3.45 m (distance between the floor and the ceiling) the difference between this value and the length of the rope 1.19 m; it will be equal to (3.45-1.19) =2.26 m. If we take as a reference point (Ep=0) the floor of the room, then the potential energy will be equal to Ep = M * g * h, replacing values in this equation (2.5 kg * 9.81 m/s2 * 2.26 m) will be 55,42 (N * m) or Jules.
Answer:
deceleration is the opposite of acceleration
Explanation:
We know that acceleration is the increase of speed with respect to time. So deceleration must be represented on the graph as a decrease in speed over time.a
Answer:
if somthing is warm or if somthing moves it usally has energy
Answer:
the unit of force in the centimeter-gram-second system equal to the force that would give a free mass of one gram an acceleration of one centimeter per second per second.Explanation:hope its a good answer
Answer:
10512m
Explanation:
Using formula for Uniform Velocity v = D/t ;
where v = Velocity (367 m/s); D = Vertical distance (?); t = length of time of motion (?).
To find t we use the Kinematic equation D= v₀t + (1/2(at²));
where D = Distance traveled (4020m); v₀ = initial velocity (0); a = acceleration;
4020 = (0)t + (1/2(9.8)t²)
4020 = 1/2(9.8)t²
t² = 4020/(1/2(9.8))
t = √(4020/4.9).
back to our formula for Uniform Velocity v = D/t;
D = vt
D = (367)(√(4020/4.9))
D ≈ 10512m
