(1) The ball is in the air for <u>1.4 seconds.</u>

(2) The horizontal velocity of the ball as it rolls off the table is<u> 6.32 m/s.</u>

(3) The vertical velocity of the ball right before it hits the ground is <u>13.72 m/s.</u>

(4) The horizontal velocity of the ball right before it hits the ground is<u> 6.32 m/s.</u>

(5) The initial vertical velocity as soon as the ball comes of the cliff is <u>13.72 m/s​.</u>

<h3>What is the time of motion of the ball?</h3>

The time of motion of the ball is calculated by applying the following equation.

t = √(2h/g)

where;

  • h is the height of the cliff
  • g is acceleration due to gravity

t =  √(2h/g)

t = √(2 x 9.63 / 9.8)

t = 1.4 seconds

The horizontal velocity of the ball is calculated as follows;

v = d/t

where;

  • d is the horizontal distance travelled by the ball = 8.85 m

v = 8.85 m / 1.4 s

v = 6.32 m/s

The vertical velocity of the ball before it hits the ground is calculated as;

vf = vi + gt

vf = 0 + 9.8 x 1.4

vf = 13.72 m/s

The horizontal velocity of the ball right before it hits the ground is calculated as;

the initial velocity of a projectile = final horizontal velocity

vxf = vxi = 6.32 m/s

The initial vertical velocity as soon as the ball comes off the cliff = final vertical velocity = 13.72 m/s

Robert Hook discovered cells when viewing a _____ under a microscope.
sp2606 [1]
<span>What you need to do while answering this questions, is ask yourself what has cells - only if a thing has cells can you see those cells under a microscope. Objects of animal and plant origin have cells, so blood, plant and cork (made of tree bark) can have cells, and a box too, if it's made of wood. So we can''t exclude any answers based on this. We must then know the story of Robert Hook - and it was in fact a cork. He did this discovery around 1655. At the time his main interest was the microscope rather than the cork, and he used to cork to demonstrate the function of the microscope. The correct answer is CORK.</span>
