The direction the horse travels has nothing to do with its speed but...
The horse would be traveling 6.25 km/hr
You simply take the overall travel (25km) and divide it by the total time (4hr)
You get 6.25km as your answer, meaning that every hour the horse traveled 6.25km every hour.
4 hours later the horse has reached 25km
Answer:
Explanation:
Let the radius of the hemisphere is R. The mass is released from rest so the initial speed is equal to zero and acceleration is equal to the g.
By the Newton's 3rd equation,
Now, at the bottom hemisphere the centripetal acceleration will act on the mass and the direction of this force is towards center,
Hence, the acceleration on the bottom of the hemisphere is equal to the 2g.

Answer:
10 degree C
Explanation:
Q = 500 kcal = 500 x 1000 x 4.186 J = 2.1 x 10^6 J
V = 50 liter
m = Volume x density = 50 x 10^3 x 1000 = 50 kg
Let ΔT be the rise in temperature.
Specific heat of water = 4186 J/kg C
Q = m x c x ΔT
2.1 x 10^6 = 50 x 4186 x ΔT
ΔT = 10 degree C
