A ball is projected horizontally from the top a hill with a velocity of 30mls. If it reaches the ground 5seconds later, the height of the hill is?
y = 1/2 (9.8)(5^2)
The 30 m/s is there to confuse and annoy you.
To solve this problem, we can use the kinematic equation for horizontal motion:
Distance = Velocity × Time
In this case, the distance the ball travels horizontally is the height of the hill. The velocity is given as 30 m/s, and the time it takes to reach the ground is 5 seconds.
Therefore, we can calculate the height of the hill using the formula:
Distance = 30 m/s × 5 s
Distance = 150 m
So, the height of the hill is 150 meters.
