Suppose a free-fall ride at an amusement park starts at rest and is in free fall. What is the velocity of the ride after 2.3 s?
horsena [70]

Answer:

V = a * t = 9.8 m/s^2 * 2.3 s = 22.5 m/s   velocity after 2.3 s

S = 1/2 g t^2      since initial speed is zero

S = 1/2 * 9.8 m/s^2 * 5.29 s^2 = 25.9 m

How much would a 75kg man weigh due to the effect of gravity
Nezavi [6.7K]

Answer: 735 N

Explanation:

Weight W is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass m of the body by the acceleration of gravity g:  

W=m.g

In the case of our planet Earth, the acceleration due gravity is g=9.8 m/s^{2}. So for a man whose mass is m=75 kg, his weight is:

W=(75 kg)(9.8 m/s^{2})

W=735 N

klio [65]

Answer:

B is correct

Explanation:

Battery contains sulfuric acid H2SO4. As the battery cools and eats with the running of the motor, hydrogen gasses is released from electrolytic reactions and escapes through the vents. it mixes with other particulates. The mixtures react at the electrical terminals of the battery and corrosion is formed.

Corrosion can be prevented by the addition of anti corrosion gel. It can also be removed by scrubbing the terminals with a hard brush
