hope i'm not too late!!
Answer:
Not balanced
Explanation:
The force pulling the object up is applying less force than the object pulling down, this means the object will move down
Answer:
50.2 m/s
Explanation:
First of all, we need to find the time it takes for the ball to reach the ground.
The vertical position of the ball at time t is given by
where
h = 120 m is the initial height
u = 0 is the initial vertical velocity
g = -9.8 m/s^2 is the acceleration of gravity
The ball reaches the ground when y = 0. Substituting into the equation and solving for t, we find the time of light:
The vertical component of the velocity of the ball changes following the equation
Substituting t = 4.95 s, we find the final vertical velocity of the ball just before reaching the ground:
where the negative sign means the direction is downward.
We also can find the horizontal component of the velocity: since we know the horizontal distance travelled is d = 64 m,
And the final speed is calculated as the magnitude of the resultant of the two components of the velocity:
Newton's second law on motion states that a<span>cceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
So to put it in super simple terms, p</span><span>ushing or pulling an object produces acceleration, a change in the speed of motion.</span>
