Question

An object is thrown upward with a speed of 12 m/s on the surface of planet X where the acceleration due to gravity is 1.5 m/s^2. How long does it take for the object to reach the maximum height?

Answer 1

\[V_{final}=V_{initial}+a*t\]

you can use this equation to find the time it takes to reach maximum height, happens when V_final = 0 think about why

Answer 2

acceleration is -1.5 m/s^2 as its due to gravity and is downward, if u take up to be positive, the object's initial velocity12m/s up,
