When a 1984 alfa romeo spider sports car accelerates at the maximum possible rate, its motion during the first 20 is extremely well modeled by the simple equation v2x=2pmt where p=3.6104w is the car's power output, m = 1200kg is its mass, and vx is in m/s. that is, the square of the car's velocity increases linearly with time.
a) what is the car's speed at t=11 s ?
b) what is the car's speed at t=18 s ?
c)find a symbolic expression, in terms of p, m, and t, for the car's acceleration at time t.
d)evaluate the acceleration at t=1.0 s .
e) evaluate the acceleration at t=10 s .
