Step 1
Siolve the given equation d=9.8t215t+100 as,
9.8t215t+100=0
9.8t2+15t100=0
t=15±225+400(9.8)2(9.8)
t=15±64.3919.6
t=2.52, t=4.05
Step 2
The negative value of t can be neglected since time cannot be negative. Thus both the values of t do not make sense. Therefore, the values of t are 2.52 seconds.
