Hope this helps you out, dear. Have a beautiful day!!
D. There is an overall release of energy when bonds form.
d = distance = 0.76 m <span>
<span>a = acceleration due to gravity = 9.81 m/s^2</span>
u = initial velocity = 0 (as the ball rolls off the table the
vertical velocity = 0
t = time = missing so we need to solve it
So we use the equation d = ut + 1/2 at², and ever since u is
zero, ut is zero and the equation becomes to d = 1/2 at² and this reorders to t
= sqrt (2d/a) = 0.39 seconds.
Since there are no forces performing in the horizontal
direction, this means that there is no acceleration in the horizontal direction
and consequently the horizontal velocity is persistent. </span>
Velocity = distance/
time.
Horizontal velocity is
therefore horizontal distance/time = 0.61 m/0.39s = 1.56 m/s.

Answer:
<h3>The answer is 2800 kg</h3>
Explanation:
The mass of the truck can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>2800 kg</h3>
