Question

a motorcyclist traveling at 25m/s accelerates at a rate of 7m/s2 for 6 seconds what is the final speed of the motorcycle

Answer 1

Answer:

67 m/s

Step-by-step explanation:

Speed i = 25 m/s

acceleration = 7m/s^2

t = 6s

t after 1 second of acceleration = 25 + 7 = 32m/s

t after 2 seconds of acceleration = 32 + 7 = 39m/s

t after 3 seconds of acceleration = 39 + 7 = 46m/s

t after 4 seconds of acceleration = 46 + 7 = 53m/s

t after 5 seconds of acceleration = 53 + 7 = 60m/s

t after 6 seconds of acceleration = 60 + 7 = 67m/s

∴Final velocity = 67 m/s after 6s
