Explanation:
Answer:he's not applying force or motion
Explanation:
p=f & m
Answer:
The K.E of the bowling ball right before it hits the ground, K.E = 2450 J
Explanation:
Given data,
The mass of the bowling ball, m = 10 kg
The height of the building, h = 25 m
The total mechanical energy of the body is given by,
E = P.E + K.E
At height 'h' the P.E is maximum and the K.E is zero,
According to the law of conservation of energy, the K.E at the ground before hitting the ground is equal to the P.E at 'h'
Therefore, P.E at 'h'
P.E = mgh
= 10 x 9.8 x 25
= 2450 J
Hence, the K.E of the bowling ball right before it hits the ground, K.E = 2450 J
The metallic elements which all react to water are found in the same group, the groups name is the Alkali metals, or also known as group one.
Answer:
work = 500*3 = 1500 J
1500J in 5 sec = 300 watts
