Answer:

216,890 J

Explanation:

We first define the Kinetic Energy Formula:

K.E =

\frac{1}{2} m {v}^{2}

where m is the mass of the object in kg, and v is the velocity in m/s.

Given from the information from the question, we substitute the values in to find K.E.

K.E of car =

\frac{1}{2} (820) {(23)}^{2}  \\  = 216890 \: joules

Note that the SI unit for Energy is Joules or J.

A 7 kg ball is moving at a constant speed of 5 m/s. A force of 300 N is applied to the ball for 4 s. The new speed of the ball i
olasank [31]

Answer:

The new speed of the ball is 176.43 m/s

Explanation:

Given;

mass of the ball, m = 7 kg

initial speed of the ball, u = 5 m/s

applied force, F = 300 N

time of force action on the ball, t = 4 s

Apply Newton's second law of motion;

F = ma = \frac{m(v-u)}{t}\\\\m(v-u) = Ft\\\\v-u = \frac{Ft}{m}\\\\v =  \frac{Ft}{m} + u

where;

v is new speed of the ball

v =  \frac{Ft}{m} + u\\\\v =\frac{300*4}{7} + 5\\\\v = 176.43 \ m/s

Therefore, the new speed of the ball is 176.43 m/s
