Answer 1

hey u know the formula of total energy

Answer 2

nop sry......

Answer 3

ok
total energy=kinetic +potential energy

Answer 4

k

Answer 5

total energy =1/2(mv^2) +mgh
using this formula

Answer 6

is 216 J the answer ??????

Answer 7

*596J nt 216

Answer 8

can u calculate

Answer 9

i did...... jst to knw if it is right ??/

Answer 10

TE = 1/2 mv^2 + mgh
=1/2 x 2 x (20)^2 + 2 x 9.8 x 10
=400+196
=596J
am i right????????????? O.o

Answer 11

u there???????

Answer 12

v=72 use

Answer 13

but it is 72 km/hr......shoudn we convert it to metre per second (m/s)

Answer 14

okk

Answer 15
