Answer:let initial velocity u=14m/s
Final velocity v=20m/s
Time taken t=30
Acceleration =a
V=u +at
a= (20-14)/30
a=0.2m/s^2
Explanation:
Acceleration is the change in velocity with respect to time.
Hello!
We can use the kinematic equation:
a = acceleration (m/s²)
vf = final velocity (45 m/s)
vi = initial velocity (25 m/s)
t = time (5 sec)
Plug in the givens:
Answer:
<u>20 m/s</u>
Explanation:
<u>Given</u>
- u(A) = 20 m/s
- u(B) = 30 m/s
- acceleration equal in magnitude but opposite in direction
<u>Solving</u>
- Velocity of A at Q = 30 m/s
- From, P to Q, <u>Δv(A) = 30 - 20 = +10 m/s</u>
- Therefore, velocity of B at Q will be decreased by 10 as it is equal in magnitude but opposite in direction to A
- Δv(B) = v(B at Q) - u(B at P)
- -10 m/s = v(B at Q) - 30 m/s
- v(B at Q) = 30 - 10 = <u>20 m/s</u>
When the canoe leaked, the boat
sank because it has a leak. The boat must have a strong base at its bottom to
enable itself to float. If this is damaged, the water can now enter due to the
hole thereby increasing the velocity of water coming in.
