Question
A body of mass 2 kg is projected with a velocity 60 m/sec at an angle of 30°. What is the height of the body from ground at t = 2·5s? (Take g = 10 m/s2)
Solution
The height of the body from ground at any instant is given by,

... (1)
Given that,
Mass of the body, m = 2 kg
Time, t = 2.5s
Acceleration due to gravity,
Putting this in equation (1), we will get the height of the body from the ground,
