rightwards is the positive velocity
Rightwards is the positive elicitation:
Answer:
The answer is A
Explanation: hope this helps :)
Answer:
we know formula for mechanical energy , E( Mechanical) = U + K , where U is the potential energy and K is the kinetic energy!
So E = 30.7 J + 128.4 J = 159.1 J
The kitten's velocity is V=0.625 m/s
<u>Explanation:</u>
<u>Solving the problem,</u>
Given
Mass=0.8 kg
Momentum=0.5 kg.m/s
Velocity=?
We have the formula,
P=M*V
V=P/M
V=0.5 kg.m/s/0.8 kg
V=0.625 m/s
The kitten's velocity is V=0.625 m/s

Answer:
Explanation:
When the ball is thrown upwards it's velocity is pointing upwards while acceleration i.e. acceleration due to gravity is pointing downwards.
As the ball moves upwards it's velocity is decreasing and the ball reaches maximum height it's velocity becomes zero while the acceleration is still pointing downwards.
During downward motion, both velocity and acceleration are pointing downward.
