Answer:
50.5 m
Explanation:
We are given that
Velocity=v=19.5m
Vertical component of initial velocity=
Height=h=-14.5 m
Acceleration due to gravity=
By solving we get
Time cannot be negative
Therefore, time=3.1 s
Horizontal component of velocity=
Distance=
Hence, the golf ball travel horizontally before it hits the water=50.5 m
Answer:
It gets refracted.
Explanation:
When light beam travels through different mediums they refract i.e. they change their direction. Here the angle of incidence is less than 90°. After entering the glass slab the light beam will move towards the normal (a line drawn perpendicular to the interface of the two mediums). Thus the angle of refraction will be even lesser than angle of incidence.
Answer:
714s
Explanation:
t=H/v=500000m/700m/s=714s
