Given that:
time (t) = 20 s ,
S = ?
We know that S = ut + 1/2 at² meters
since free fall, a = g = 9.81 m/s² ; u =0 ;
S = 0 + 1/2 × 9.81 × 20²
<em> S= 1962 m</em>

Answer:
x = 45 MPH
Explanation:
given,
Average speed of the first half = 75 MPH
Average speed of entire ride = 60 MPH
Average speed of the second half = ?
let the average speed of the second half = x MPH
now,
average of entire ride is given as 60 mph so,


75 + x = 120
x = 120 -75
x = 45 MPH
hence, the average speed of the second half comes out to be 45 MPH.
Answer:6m/s^2
Explanation:
Mass =3kg
Force=18N
Acceleration =force ➗ mass
Acceleration =18 ➗ 3
Acceleration =6
Acceleration =6m/s^2
