Answer:
Potential energy only
Explanation:
at the top of its swing the pendulum stops moving , (therefore it has no KINETIC energy) thus all of the energy is stored as potential energy.

Answer:
20m/s
Explanation:
acceleration=final velocity-initial velocity/time
4.0m/s²=v m/s-0m/s/5.0sec
5.0sec×4.0m/s²=v m/s-0m/s×5.0m/s/5.0m/s
20m/s=v
Answer:
Weight = 3.92 N
Explanation:
Given:
Mass m = 0.4 kg
Acceleration due to gravity g = 9.8 m/s²
Find:
Weight
Computation:
Weight = Mass x Acceleration due to gravity
Weight = 0.4 x 9.8
Weight = 3.92 N
