Billy drops a water balloon from the roof of his house. Since the balloon began with an original velocity of zero, 30.6 meters far above the ground was the balloon dropped if it took 2.5 seconds to hit the ground.
Solution:
Distance = (1/2) (gravity) (time)²
= (1/2) (9.8 m/s²) (2.5 sec)²
= (4.9 m/s²) (6.25 sec²)
= 30.6 meters (answer)

The force of gravity acting on a child's Mass on Earth is 490 Newtons. What's the child's Mass?
Weegy: If the force of gravity acting on a child's Mass on Earth is 490 Newtons.The child's Mass (m) will be: 50 kg. Force (F) = 490N; Gravity (g) = 9.8 m/s/s. Formula: m = F/g. Substitution: m = 490 N/9.8 m/s2. Answer: 50 kg. (More)

2.48 MJ of heat energy is needed to convert 7 kilograms of ice at 9 C to water at 0 C.

Solution:
Q = mLf+mci T
Q = (7 kg*3.34×10 J/kg) + ((7kg*2100J/kgK*{0°C-(9°C)})
= 2.48 MJ (MEGA JOULES).
