DENIUS [597]

Answer:

The answer to your question is:      Ep = 14715 Joules

Explanation:

Data

mass = 50 kg

Potential energy = ?

height = 30 m

g = 9.81 m/s²

Equation

                Ep = mgh

Substitution

                     Ep = (50)(9.81)(30)

                     Ep = 14715 Joules

Anettt [7]

Answer:

The speed of the automobile after 1.43s is 10 \frac{m}{s}

Explanation:

a= \frac{-f}{m}= \frac{-u_{k}*m*g}{m}

a= -u_{k}*g=- 0.590* 9.8 \frac{m}{s^{2} }= -5.782 \frac{m}{s^{2} }

V_{f} = V_{i} + a*t

V_{f} = 18.2 \frac{m}{s} - (5.782 \frac{m}{s^{2} }* 1.43 s)

V_{f} = 9.93174 \frac{m}{s}

V_{f} ≅ 10 \frac{m}{s}
