Question

Asked Oct 24, 2019

When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation: v^{2}_{x} =(2P/m)*t

where P=3.6×10^{4} W is the car's power output, m = 1200kg is its mass, and v_{x} is in m/s. That is, the square of the car's velocity increases linearly with time

Find a *symbolic expression,* in terms of P, m, and t, for the car's acceleration at time t.

Step 1

Given,

Step 2

The velocity of the car,

Step 3

Now, acceleratio...
