if an object is projected upwards with an angle 30 to the horizontal and its initial velocity is 20 m/s, its maximum height= ? ( consider g= 10m/s^2 )

Explanation:

Projectile Motion

It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path under the action of gravity.

The maximum height hm is reached when the vertical component of the velocity is 0. It can be calculated as follows:

Where:

vo = initial speed of the object

θ   = initial launch angle

g   = acceleration of gravity ()

The object is projected with an angle of θ=30° and an initial speed of vo=20 m/s. The maximum height is:
