The sports car starts from rest and travels along a straight road. Its initial increasing acceleration is caused by the rear wheels of the car as shown on the graph in (Eigure 1). Figure a (m/s²) 10 0 10 15 s (m) 1 of 1
What is the velocity of the car when s= 15 m? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) Y Hint 1. How to approach the problem When the a-s graph is given, the points on the v-s graph can be determined by using v dv = a ds. Integrating this equation between the limits v = vo at s = 80 and v = v₁ at s = $1, obtain the equation that relates the initial velocity, final velocity, and acceleration. -- Submit HA W ? V = 0 m/s You may have assumed that velocity is zero when acceleration is constant. Actually, acceleration is zero when velocity is constant, not vice versa. No credit lost. Try again.
