Answer: 7.407 m/s^{2}

Explanation:

In this question we are asked to find the cheeta's accelaration and we assume it is constant. Therefore, we can use the folowing equation:

V=V_{o}+at (1)

Where:

V=80 \frac{km}{h} \frac{1000 m}{1 km} \frac{1 h}{3600 s}=22.22 m/s is the cheeta's final speed

V_{o}= 0 m/s is the cheeta's initial speed

t=3 s is the time in which the cheeta passes from V_{o} to V

a is the cheeta's acceleration

Isolating a from (1):

a=\frac{V}{t} (2)

a=\frac{22.22 m/s}{3 s} (3)

Finally:

a+7.407 m/s^{2}

Lelechka [254]

Answer:

1 joule = 0.737 foot-pound

Joule is the unit of work.

1 J = 1 N·m

In SI units

1 J = 1 kg· m/s²

0.737 foot-pound is the amount of work to raise 0.737 pounds one foot or raising one pound to 0.737 ft.
