Question

A train accelerates at -1.5 m/s2 for 10 seconds. If the train had an initial  speed of 32 m/s, what is its new speed?  A. 17 m/s  B. 15 m/s  C. 47 m/s  D. 32 m/s

ngockhue · Answer

Answer:   17 m/s   Explanation:   Using formula a = (v-u) /t  acceleration a =  -1.5 m/s2  final velocity v = unknown  initial velocity u = 32 m/s  time t = 10s    -1.5 = (v-32)/10  -15 = v - 32  -15 + 32 = v  v = 17 m/s
