Question

The Lamborghini Murcielago can accelerate from 0 to 27.8 m/s (100 km/hr or 62.2 mi/hr) in a time of 3.40 seconds. How fast will the car be traveling (m/s) after 5.1 seconds.

Answer 1

V = Vo + a*t = 27.8
0 + a*3.4 = 27.8
a = 8.18 m/s^2.

V = Vo + a*t = 0 + 8.18*5.1 = 41.70 m/s.

Answer 2

A car moves at 15 m/s and coasts up a hill with a uniform acceleration of -2.7 m/s2. What is its displacement after 5.1 seconds?
