Question

1. An object is thrown upward with a speed of 17 m/s. After t seconds, its height can be solved using the formula
h = 17t − 4.9t², where h is the height and t is the time. After how many seconds is the object strikes the ground whenthrown 9.8 meters high?

2. An object is thrown upward with a speed of 20 m/s. After t seconds, its height can be solved using the formula
h = 20t − 4.9t², where h is the height and t is the time. After how many seconds does the object strikes the groundwhen thrown 19.6 meters high?
