TRUE AND FALSE QUESTIONS IN PHYSICS 6. Change in mass affects KE more than a change in velocity
7. For acceleration due to gravity on Earth (g), we use 9.8 m/s^2
8. In a closed system, we can say that the maximum amount of Kinetic Energy must equal the maximum amount of Potential Energy in a different part of the closed system
9. The P in GEWAUP stands for Practice. 10. 1st Law of Thermodynamics states that energy cannot be created or destroyed.​

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
