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 mph

(a). We need to calculate the power when velocity is 10 mph

Using formula of power

$P=F\times v$

Where, F = force

v = velocity

P = power

Put the value into the formula

$P= 13433.6\times10\times 0.44704$

$P=60053.56\ Watt$

(b). We need to calculate the power when the velocity is 100 mph

Using formula of power

$P=F\times v$

Where, F = force

v = velocity

P = power

Put the value into the formula

$P= 13433.6\times 100\times0.44704$

$P=600535.65\ Watt$

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

(b). The power is 600535.65 watt.
