Explanation:
You COULD find acceleration by taking a lot of distance measurements,
but that's definitely the hard way to do it.
Acceleration is (change in speed) divided by (time for the change).
So the basic way to calculate acceleration is to measure the change
in speed, not distance.
I think it is False because as the Gad relajases fuel it doesn’t move as much anymore
The person running towards the trumpet, Mr. C,
hears a higher frequency.
The person running away from the trumpet, Mrs. B,

The trumpeter, Mr. A, and the person who is just standing still
and listening, Miss D, both hears the beautiful perfect B-flat.
Answer:
Explanation:
distance travelled
s = 2πR
= 2 X 3.14 X 140
= 880 m
final velocity = v
initial velocity = u
distance travelled = s
time = 60 s
s = ut + 1/2 at²
880 = .5 x a x 60²
a = .244 m/s²
final velocity v = at
= .244 x 60
= 14.66
centripetal acceleration at final moment
v² /R
14.66 X 14.66 / 140
= 1.53 m/s⁻²
1.53 m/s²
this is centripetal acceleration which acts towards the centre.
tangential acceleration calculated a _t = .244
redial acceleration ( centripetal ) = 1.53
Resultant acceleration
R²= 1.53² + .244 ²
R = 1.55 m/s²
total force = 1.55 x 76
= 118 N
