Question

A ball is thrown vertically upward with a velocity of 30 M S calculate the time taken to reach maximum height​

Answer 1

Answer:

Given :

u = 30m/s

g = 10m/s^2

v = 0m/s

t = ?

h = ?

1st , we find out the time , applying formula :

t = v - u / g

t = 0m/s - 30m/s / -10m/s^2

t = 3s

2nd , we calculate the height :

2gh = v^2 - u^2

2*-10m/s^2*h = (0m/s)^2 - (30m/s)^2

h = 900m^2/s^2/ 20m/s^2

h = 45m
