Answer:
35m/s
Explanation:
150 m/s divided by 4 is 35
Answer:0.4 m
Explanation:
Given
Maximum displacement A=0.49
The sum of kinetic and elastic potential energy is
where k=spring constant
U+K.E.=
when K.E.=U/2
K.E.=kinetic energy
U=Elastic potential Energy
When a object is slowing down the acceleration is the opposite direction as the velocity
Explanation:
If it is not slowing down its not negative
