The maximum upward acceleration that the elevator can have without breaking is = 10.36m/s².
<h3>How to calculate maximum upward acceleration?</h3>
To calculate the maximum acceleration of the elevator we must take into account Newton's second law and its formula that takes into account the following aspects:
- F = Is the force applied in newtons.
- m = Is the mass of the object in kilograms.
- a = Is the acceleration of the object in meters per second squeared.
According to the above, we apply the values we have as follows:
- a =

- a =

Answer:
30 kgm/s
Explanation:
The momentum of a body is given by the product of mass and its velocity.
∴ momentum = mv
= 15 × 2
= 30 kgm/s
The option that describes volume is B. the amount of space that matter occupies.
It refers to the area within which some body is contained, and is usually measured in cubic meters, or any variation of the meter.
Answer:
one ninth
Explanation:
d = 1 cm , v = v
D = 3d, V = ?
By the equation of continuity,
A V = a v
3.14 x D^2 / 4 x V = 3.14 x d^2 / 4 x v
9d^2 x V = d^2 x v
V = v / 9
Thus, the velocity becomes one ninth the initial velocity
