I think 100,375 J.
Hope it helps :)
Answer:
Check the explanation
Explanation:
Their is no data provided for the mass and length of pendulum in the picture.but it is very easy to check kinetic energy.KE is mv^2/2, m is the pendulum Bob and v is time dependent ,equation of displacement of SHM is given as x(t)=Asin(wt+∆) where ∆ is the phase angle now v=dX/dt _v=Awcos(wt+∆) and KE=
Thus w angular frequency of oscillation is√(g/l)
g acceleration due to gravity and l length of pendulum.so KE is same for pendulum having same mass and length otherwise KE expression with time will vary for all other cases.now check if all experiment pendulum have same mass and length otherwise KE will not be same.You can now easily verify.
Answer:
Two cars of equal weight and braking ability are travelling along the same road but combined with other factors it could mean the difference between life.
Answer:
sry.............................................
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
= (140 km/hr) - (10 km/hr) = 130 km/hr
Time for the change = 50 sec
Acceleration = (130 km/hr) / (50 sec) = 2.6 km/hr per second.
To convert to more familiar units:
(2.6 km/hr-sec) x (1000 m/km) x (1 hr/3600 sec)
= (2.6 x 1000 x 1) / (3600) km-m-hr / hr-sec-km-sec
= 0.722 m/s² (about 0.074 of a G)
