<u>Final Velocity = 14m/s</u>
<u>Displacement = 56m</u>
Explanation:
U (initial velocity) = 2m/s
A (acceleration) = 3m/s^2
T (time) = 4s
v (final velocity) = ?
S (displacement) = ?
<u>FIRST FIND FINAL VELOCITY:</u>
(i) Multiply both sides by t:
(ii) Add u to both sides:
(iii) rearrange formula:
v = ( 3 × 4 ) + 2
v = 12 + 2
<u>v = 14m/s</u>
<u>SECOND FIND DISPLACEMENT:</u>
(i) Multiply both sides by t:
(ii) Rearrange formula:
s = 14 × 4
<u>s = 56m</u>
Not sure why it isn't one of the options but im pretty sure I did all the steps right...
Answer:Balance Forces
Explanation:
Balanced Forces are equal in magnitude and opposite in direction that acts on the same body. Whenever balanced forces act on an object the object is either still or moving in the same direction with constant velocity.
example of Balanced Forces are
- Consider a block lying on the ground and is being pulled by two forces of equal magnitude but in acting in the opposite direction. As a result, the block is at rest.
Expand each vector into their component forms:
Similarly,
Then assuming the resultant vector is the sum of these three vectors, we have
and so has magnitude
and direction such that
