(a) Find the PE at A PE = m g h = ( 500 kg )( 9.8 m/s2 )( 30 m )
A B C (a) Find the PE at A PE = m g h = ( 500 kg )( 9.8 m/s2 )( 30 m ) PE = J
2
(c) the Total Energy at A
500 kg 30 m 18 m A B C (b) the KE at A v = 0 KE = 0 (c) the Total Energy at A Total Energy = PE + KE = J + 0 Total Energy = J
3
(d) the PE at B h = 0 PE = 0 (e) the KE at B Total Energy = PE + KE
500 kg 30 m 18 m A B C (d) the PE at B h = 0 PE = 0 (e) the KE at B Total Energy = PE + KE J = KE KE = J
4
(f) the speed at B 2 KE 2 ( 147 000 J ) v = = m 500 kg v = 24.2 m/s
A B C (f) the speed at B 2 KE 2 ( J ) v = = m 500 kg v = m/s
5
(g) the PE at C PE = m g h = ( 500 kg )( 9.8 m/s2 )( 18 m )
A B C (g) the PE at C PE = m g h = ( 500 kg )( 9.8 m/s2 )( 18 m ) PE = J
6
(h) the KE at C Total Energy = PE + KE 147 000 J = 88 200 J + KE
500 kg 30 m 18 m A B C (h) the KE at C Total Energy = PE + KE J = J + KE J J KE = J
7
(i) the speed at C 2 KE 2 ( 58 800 J ) v = = m 500 kg v = 15.3 m/s
A B C (i) the speed at C 2 KE 2 ( J ) v = = m 500 kg v = m/s
