Answer:
The distance from the building is 11.41 m.
Step-by-step explanation:
Given that,
Speed = 30.0 m/s
Angle = 45.0°
Distance = 10.0 m
We need to calculate the vertical component
Using formula of vertical component



We need to calculate the time
Using equation of motion

Put the value into the formula




On neglecting of higher value of t
Then use the horizontal component



We need to calculate the distance

Put the value into the formula


Hence, The distance from the building is 11.41 m.
