Robert threw the Frisbee at 10 m/s.
This is because the formula for average speed is: v = d/t
v = Average speed or average velocity
d = Distance
t = Time
so the formula would say v = 50m/5s; v = 10m/s
3, protons are positive and there are 3 positive atoms visible
Answer:
Explanation:
a)
Apply the law of conservation of momentum
Since there is no external force(friction) oon the system, Momentum in horizontal direction must remain constant.
Initial Momentum = Final Momentum
b)
Apply law of conservation of energy
Loss in Potential Energy = Gain in Kinetic Energy
334kJ ------ 1kg
x. ------- 0,1kg
x = 33,4kJ
is it right?
