The correct answer should be A
Answer:
a = 1.16 m/s²
Explanation:
In order to find the acceleration of the ball we will use 3rd equation of motion.
2as = Vf² - Vi²
where,
a = acceleration = ?
s = displacement = 21.9 m
Vf = Final Velocity = 7.14 m/s
Vi = Initial Velocity = 0 m/s (Since, ball starts from rest)
Therefore, using the values, we get:
2a(21.9 m) = (7.14 m/s)² - (0 m/s)²
a = (50.97 m²/s²)/(43.8 m)
<u>a = 1.16 m/s²</u>
<span>The answers are:
bulb, motor, buzzer and swtich.As seen in the picture attached,
The electric current leaves the battery passes through
the bulb. It then travels through the
motor, next through the
buzzer and finally passes through the
switch before returning to the battery.</span>
Answer:
the swing on the right is more likely to break
since the vertical component of the tension of the rope has to balance the weight. ie. the resultant tension in the rope is greater
1. The speed is at a constant rate same with the acceleration and velocity
2. When there getting close to the top there speed, acceleration, and velocity all start to decrease
3. The speed and acceleration and velocity all on the way down drastically increase number
