Question

a car starting from rest has a constand acceleration a1 for a time
t1 during which it covers a distance s1 in the next tine interval
t2 the car has a constant retardation a2 and comes to rest after
covering a distance s2 in th etime comes to rest after covering a
distance s2 in the time t2what would reltation in them

Suppose v is the maximum velocity
 So we havev=a1t1=a2t2  
 (1)angain distance travelled is given byv2=2as=2a1s1=2a2s2  or  a1s1=a2s2
 (2)Dividing equation (2) by (1) we haves1t1=s2t2So those are the relation between them
