Answer: 79 J
Explanation:
The value of the kinetic energy at the bottom would be equal to the value of potential energy at the top. This comes from the conservation of energy. At the top, the bob of mass just has potential energy due to its position. At the bottom, potential energy converts entirely to kinetic energy due to its motion.
It is given that mass of the bob is, m = 0.18 kg
height from which it is dropped is, h = 45 m
acceleration due to gravity, g = 9.8 m/s²
Thus, K.E. = P.E. = m g h = 0.18 kg× 45 m × 9.8 m/s² = 79 J
I think the best word here would be compress. It is to compress that is defined as to squeeze a gas into a smaller space. Compression is the reduction of volume which cause an increase in pressure of the gas. Hope this answers the question. Have a nice day.
Answer:
11m/s^2
Explanation:
Acceleration can be calculated by diving speed by time. Since we know speed and time, acceleration can be calculated.
55/5 = 11m/s^2
Answer:
the correct answer is 3 meters
