1.	X=2+5t+7t^2 calculate magnitude of initial velocity
Answer» Answer: Explanation: dx/dt=0 0–5+12t=0 t=5/12 seconds Acc.=12m/s2 V=0 V=u+at 0=u+12×5/12 U= -5m/s once TRY this model and formula confirm you will GET the answer

Answer»

Answer:

Explanation:

dx/dt=0

0–5+12t=0

t=5/12 seconds

Acc.=12m/s2

V=0

V=u+at

0=u+12×5/12

U= -5m/s

once TRY this model and formula confirm you will GET the answer
