Answer:
Acceleration of the elevator = 13.242 m/s2.
Explanation:
Force is defined as the push or pull on an object with mass in kg that causes a change velocity. Force as a vector means it has both magnitude and direction.
Mathematically,
F = M*a
Where
F = force in Newton.
M = mass of the object in kg.
a = acceleration due to gravity in 9.81 m/s2.
Acceleration of the elevator = 821/62
= 13.242 m/s2.
Answer: Distance is the actual position traveled by an object. Displacement is the shortest distance covered by the object.
Explanation:
Distance is the actual length covered by an object from one position to another. It is a scalar quantity. It cannot be negative.
Displacement is the shortest distance covered by the object. The displacement can be calculated by subtracting initial distance from the final distance. It is vector quantity. The displacement covered by an object can be zero, negative and positive.
Suppose, the boy travels from home to school then come back to his home. The distance between from his home to his school is 3 km.
In this case, the boy covers the total distance from home to school then to home is 6 km. But the displacement is zero because he comes to same position.
Answer:
The angular acceleration is final angular speed is
Explanation:
Here we know that
.............. 1
Upon substituting these values in equation 1 we get .
For calculating angular velocity we know that
.
Answer:
S = V0 t + 1/2 a t^2
S = 5 m/s * 300 s + 1/2 * 1.2 m/s * (300 s^2)
S = 1500 m + .6 * 90000 m = 55,500 m
Check: V0 = 5 m/s
V2 = V0 + a t = 5 + 1.2 * 300 = 365 m/s
Vav = (V1 + V2) / 2 = (5 + 365) / 2 = 185 m/s (note uniform motion)
S = 185 * 300 = 55,500 m
We calculated V2 above at 365 m/s the speed after 300 sec
