Answer:
Im acually a pilot and i do not know this that well, but it was to do with the atmosphere
Explanation:
Answer:
Final velocity of both goalie & puck = 0.018116 m/s
Explanation:
M1U1 + M2U2 = (M1+M2)V
70 x 0 + 0.17 x 33.5 = (70+0.17)V
V = 0.08116m/s
Answer:
Kinetic energy = 127.89 Joules
Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec
Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules
Hope this helps :)
Sound waves move through molecules. When there are no molecules in a certain space, sound cannot travel - whether in a vacuum or in space.
V=v0+at=38m/s;
v^2=v0^2+2ad=>d=(v^2-v0^2)/2a=544/4=68m
