Distance, since distance represents how far something has travelled, which would be in our case 2.5m.
Answer: 1.4mi/hr²
Explanation:
Blank 1: We know that acceleration is the change in velocity/change in time
Using this, we know that the acceleration will be: (50-15)/25 = 1.4
Blank 2: mi/hr²
Verrrrry interesting question !
Force= (mass) x (acceleration)
(49.5kg) x (1.3 m/s²) =
<u> Net</u> force on the box is <u>64.25 newtons upward</u>.
That's the <u>net</u> force. It's the combination of the tension in the rope
pulling the box up, and the force of gravity pulling the box down.
Force of gravity = "weight" = (mass) x (gravity) =
(49.5) x (9.8) = <u>485.1 newtons downward</u>
The tension in the rope must be enough to balance the downward force
of gravity PLUS provide another 64.25 newtons upward.
<em>Tension =</em> (485.1) + (64.25) = <em>549.35 newtons</em>
