Answer:
Acceleration is 7.990487515m/s²
Initial velocity is 0m.s
Explanation:
s=ut+(1/2)at²
210=0(7.25)+(1/2)a(7.25²)
210=26.28125a
∴a=7.990487515m/s²
'Vi' or 'u' is the inital speed. Since it starts from rest, this equals 0.
d. natural gas is the answer
Answer:
Explanation:
Formula for AVERAGE acceleration
is Final Velocity
is Initial Velocity
is Final Time
is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
a) The velocity of the boat relative to the shore is 3.40 m/s and b) The position of the boat relative to its point of origin after 3s is 10.20m.
Here it is given that the speed of the boat (x) = 2.20m/s
The speed of the stream current (y) = 1.20m/s
a) We have to find the velocity of the boat relative to the shore.
The speed of the boat = x + y
= 2.20 + 1.20
= 3.40m/s
b) Now we have to find the position of the boat after 3s
The formula for speed:
Speed = Distance/ Time
distance = speed × time
speed = 3.40m/s
Time = 3s
distance = 3.40 × 3
= 10.20 m
Therefore we get a) speed as 3.40m/s and b) distance as 10.20m.
