Question

Consider the Corvette (w=3020 lbs) having constant acceleration of a=0.91g a) What is the power when v=10 mph? b) What is the power output when v=100 mph?

Answer 1

Given that,

Weight = 3020 lbs

$3020\ lbs = 13433.6\ N$

Acceleration = 0.91 g

Velocity = 10 m/h

velocity = 4.4704\ m/s

(a). We need to calculate the power

Using formula of power

$P=F\times v$

Where, F = force

v = velocity

P = power

Put the value into the formula

$P= 13433.6\times 4.4704$

$P=60053.56\ Watt$

(b). If the velocity is

v = 100 mph

v=44.704 m/s

We need to calculate the power

Using formula of power

$P=F\times v$

Where, F = force

v = velocity

P = power

Put the value into the formula

$P= 13433.6\times 44.704$

$P=600535.65\ Watt$

Hence, (a). The power is 60053.56 watt.

(b). The power is 600535.65 watt.
