Answer: 43.01 m
Explanation:
Given that :
Time ball uses in the air = 5.93, time it takes to reach maximum height and return = time of flight(T) = 5.93 s
TIME of flight (T) = 2 * time taken(t)
Where g = a = acceleration due to gravity = 9.8m/s²
S = 0.5at²
S = maximum height
Tjme taken (t) = time of flight / 2 = 5.93/2 = 2.965 s
Hence,
S = 0.5at²
S = 2 × 0.5 × 9.8 × 2.965²
S = 43.0770025
S = 43.01 m
Answer:kinetic energy is less than Potential Energy at bottom
Explanation:
Given
Brick is drop from top of tower
suppose brick Potential Energy at top is U=C
Kinetic Energy(K) of brick is =0 at top of building
Just before hitting its Potential Energy is converted to kinetic energy and some is lost due to the friction.
Therefore kinetic Energy is less than the potential energy
at bottom K < U
Abiogenesis is the name of life on Earth.
False, sharks and remoras have a symbiotic relationship. The remora removes parasites from the sharks scales, and the shark provides protection for the remora
