A car traveling 59 km/h accelerates at the rate of 8 m/s2. How many seconds are required for the car to reach a speed of 90 km/h? ENTER NUMBERS ONLY (ONE DECIMAL PLACE). NO UNITS

Answer 1

First convert 59 km/h and 90 km/s to m/s.

59 km/h = 16.39 m/s
90 km/h = 25.00 m/s

Change in V = 8.61 m/s

8 m/s^2*T = 8.61 m/s

Solve for T, the time spent accelerating
