Question

An object starting from rest covers 20m in first two sec and 160 metres in next 4 seconds . What is its velocity after 7 second for start
You in what type of relationship brainlysirajan1​

Answer 1

Answer:

distance = 20 m

t1= 2 sec

initial velocity is zero because the object is start from rest u =0 m/s

distance2= 160 m

t2= 4 sec

v= distance *time

v= 20 *2

v= 40 m/ sec

a = v-u /t

a= 40-0/2

a=20m/s^2
