Answer:

980 kJ

Explanation:

Work = change in energy

W = mgh

W = (1000 kg/m³ × 5.0 m³) (9.8 m/s²) (20 m)

W = 980,000 J

W = 980 kJ

The pump does 980 kJ of work.

A car takes 10 s to go from v = 0 m/s to v = 25 m/s at constant acceleration. If you wish to find the distance traveled using th
german

Initial velocity (u) = 0 m/s

Final velocity (v) = 25 m/s

time taken (t) = 10s

acceleration (a) = ?

Now,

Acceleration is rate of change of velocity, so formula is

a = (v - u)/t

a = (25 - 10)/10

a = 15/10

a = 1.5 m/(s^2)

Use this value of a.
