Naim suleimangolu of turkey has a mass of about 62kg, yet he can lift 3 times this mass. If the potential energy associated with a barbell lifted 1.70 m above the floor by suleimangolu is 3.04 x 103. What is the barbells mass?

explanation:

which statement about this sum is true? −245+2.7

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
