Question

a ball is thrown upward from the ground with an initial velocity of 50m/s. what is the total time spent by the ball in the air (g=10m/s2)​

Answer 1

Answer:

$\fbox {5 seconds}$

Explanation:

The formula which is used here :

$\fbox {v = u + at}$

$\longrightarrow \textsf {v : final velocity}$

$\longrightarrow \textsf {u : initial velocity}$

$\longrightarrow \textsf {a : acceleration}$

$\longrightarrow \textsf {t : time taken}$

Solving :

v = u + at

0 = 50 + (-10)t

10t = 50

t = 5 seconds
