Answer: The velocity of the ball is 30.0 m/s
This can be calculated by using the value of acceleration as 10.0 m/s2 in free fall and the given time of 3.0 seconds. To get the
velocity, one will have to multiply the acceleration with the given time and the
quotient would result to 30.0 m/s. Mostly all object regardless of their mass,
fall to earth with the same acceleration in the absence of air resistance and as
the child drops the ball from a window, it gains speed as it falls.
Answer:
5 N acting in the same direction as the 10 N force
Explanation:
10+5=15
15=15
Answer:

Explanation:
Given:
- mass of solid disk,

- radius of disk,

- force of push applied to disk,

- distance of application of force from the center,

<em>For the condition of no slip the force of static friction must be greater than the applied force so that there is no skidding between the contact surfaces at the contact point.</em>

where:
= static frictional force




No, personal trainers and doctors have very different careers. Though they both do well for the body and health.
Answer:
AC motor........A
Explanation:
Plato, an AC motor is much simpler than a DC motor. As alternating current passes through the coil, it becomes magnetized. Since the current is alternating, the north and south ends keep switching.
