Question

An object is thrown upwards with a speed of 25 m/s. How high will it be when the speed is 12 m/s?

Answer 1

Answer:

24.05m

Explanation:

h = (v^2 - u^2)/2g. Newton third equation of motion

h = ( 12^2 - 25^2 ) / (2) (-10). g is taken negative 10 because gravity is acting in opposite direction of motion .

h = 481/20

h = 24.05 m high above the ground
