Answer:
The magnitude of the frictional force is
Explanation:
From the question we are told that
The force exerted on the box is
Generally for the box to remain at rest then it means that the frictional force is greater than or equal to the force applied to move it i.e
=>
Newton's second law states that (Force is mass times acceleration). Out of the given options, “a 10 kg ball thrown with a 50 Newton force”, an example have the greatest acceleration.
<u>Explanation:
</u>
To do the calculation, we already have the formula given derived from Newton’s second law of motion. To know the acceleration, we can simply modify the formula as,
For the 10kg ball threw in 50N, we have mass = 10 kg and Force = 50 N
Acceleration =
Similarly for 1 kg ball threw in 0.5N, substituting the values, we get
,
Acceleration =
For launching 50kg student by catapult of 100N,
acceleration =
For accelerating 500 kg car in 1000N engine,
acceleration =
Well since there are no options i would guess a cave or a space that is very empty with walls that can reflect sound
