Answer:
-2040 m/s²
Explanation:
Taking toward the wall to be positive, the initial velocity is 10.1 m/s and the final velocity is -8.3426 m/s.
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (-8.3426 m/s − 10.1 m/s) / 0.00905 s
a = -2040 m/s²
Answer:
No
Explanation:
Because the people put in charge of defining SI units said so
This would be a funny game.
Inertia, according to first Law of Newton, means that when you throw a ball it will continue moving unless a force acts over it.
Without inertia, the ball instead of continue moving, would stop as soon as it leaves your hand or foot. You had to stay pasted to the ball unitl it reaches the desired destiny for it continue moving.
Answer:
power * time = work and Power/work = time
Explanation:
In each one we are changing the way the equation is written. In power * time = work, we are isolating work and in Power/Work = time we are isolating time.
(a)The required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
<h3>What is speed?
</h3>
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.
(a)The required speed for take off will be 24.49 m/sec.
From the Newtons third equation of motion;
Hence, the required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
From the Newtons third equation of motion;
Hence, the minimum length must the runway have 193 m.
