Calculate the power a car engine contributes to speeding the 1400 kg car up to a highway speed of 60.0 mi/h in 14.0 s.

35.6 kW

Explanation:

Given data

mass (m): 1400 kg

speed (v): 60.0 mi/h. In SI units,

time (t): 14.0 s

The acceleration (a) of the car is:

The force (F) exerted is:

F = m × a = 1400 kg × 1.91 m/s² = 2.67 × 10³ N

The distance (d) travelled is:

d = 1/2 × a × t² = 1/2 × 1.91 m/s² × (14.0 s)² = 187 m

The work (w) done is:

w = F × d = 2.67 × 10³ N × 187 m = 4.99 × 10⁵ J

The power (P) of the car engine is:

P = w / t = 4.99 × 10⁵ J / 14.0 s = 3.56 × 10⁴ W = 35.6 kW

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
