Question

Give the answer with Process. ​

Answer 1

Answer:

i) Acceleration is upto 10 sec

Acceleration  =velocity/time

                       =(15-0)/(10-0)

                       =15/10

                       =1.5 m/s²

ii) De-acceleration is from 10 seconds to 16 seconds

Acceleration = (15-0)/(16-10)

                      = 15/6 =5/2

                      =2.5m/s²

De-acceleration = - Acceleration

                          = -2.5m/s²

iii) Distance covered by body = Area of Triangle under graph

                                                 = 1/2 * base * height

                                                 = (1*16*15)/2

                                                 = 240/2

                                                 = 120m
