Question

A car travels at 15 m/s for 10 s. It then speeds up with a constant acceleration of 2.0 m/s2 for 15 s. At the end of this time, what is the magnitude of its velocity? HELP

Answer 1

answers are :
a. 45 m/s
b. 15 m/s
c. 30 m/s
d. 375 m/s

Answer 2

V=V(0)+at
so we get V=15m/s+2/m^2 15s=45m/s
so a is the right answer

Answer 3

Thank you
