Question
A group of researchers launched a rocket from the ground level with starting velocity of 160 ft. After how many seconds of flight will the rocket have an altitude of 96 ft? us ethe vertical motion formula h=-16t² + vt +s where h is the altitude, v is the velocity, so because the rocket is launched from the ground and t is the time. Solution. Given: h=-16t+ vt +S 2 V = 160 ft² h = 96 ft S=0 t=? (1) By substitution 96= − 16t² + 160t +0 (2) Write the equation in standard form 16t² – 160t +96=0 (3) Solve using any method (best choice is by using the quadratic formula)
