Answer:
You should tell them that your just not interested in it anymore and that you would like to do something else besides playing guitar you should probably explain to them why you dont want to play anymore. I hoped this helped- Best of luck.

Answer:
D: 35 m/s
Explanation:
The bus is moving at a speed of 20 m/s.
Thus; v_bus = 20 m/s
Tennis ball thrown horizontally towards the front of the bus is given as 15 m/s.. Thus, v_ball = 15 m/s
No, due to the fact that the bus and the ball are moving at the same time, an observer will think the speed is the sum of that of the ball and the bus.
Thus, it will appear to an observer on the sidewalk that the speed is; v_bus + v_ball = 20 + 15 = 35 m/s
Explanation: Solution
1.
Gravitational potential energy
U=mgh=500*9.8*50
U=245000 J
2.
Kinetic energy is present at bottom of the hill
K=(1/2)mV2=(1/2)*500*27.82
K=193210 J
3.
Work done by friction
W=193210-245000=-51790 J
Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

Answer:
rev/s
Explanation:
= mass attached to each hand = 5 kg
= initial distance of masses in each hand = 1 m
= final distance of masses in each hand = 0.1 m
= moment of inertia of body = 5 kgm²
= initial total moment of inertia = 
= initial angular velocity = 1 rev/s
= final total moment of inertia = 
= final angular velocity = ?
Using conservation of angular momentum
rev/s
