A body is projected at an angle of 30degrees to the horizontal with a speed of 30m/s. What will be the angle with the horizontal after 1.5sec. Take g as 10m/s^2

Given Information:

Launch angle of projectile = 30°

Initial velocity = V₀ = 30 m/s

Acceleration due to gravity = g = 10 m/s²

Required Information:

Angle with the horizontal after 1.5 sec = ?

The angle of the projectile to the horizontal after t = 1.5 seconds is 0°

Step-by-step explanation:

The horizontal component of the velocity is given by

Where V₀ is the initial velocity and θ is the launch angle

The vertical component of the velocity is given by

Where V₀ is the initial velocity, θ is the launch angle, g is the acceleration due to gravity and t is the time.

So after t = 1.5 sec

The horizontal component of the velocity is

And the vertical component of the velocity is

The angel is

Therefore, the angle of the projectile to the horizontal after t = 1.5 seconds is 0°

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !
