Question

an object is thrown vertically upward with initial velocity of 20 m/s calculate total time it takes to return and ground take G = 10 m/s²​

Answer 1

Answer:

2sec

Step-by-step explanation:

u= 20m/s

v=0 m/s

g= -10m/s^2

t= ?

v=u+gt

t= v-u/g

t= 0-20/-10

t=2sec

Answer 2

Answer:

2sec

Step-By-Step-Explanation:

u=20m/s

g=-10m/s²

v=0

v=u + gt

t=v-u/g

t=0-20/-10

t=-20/-10

t=2sec
