F=ma
W=F*distance
375J=(45kg)(a)(5m)
a=375/(45*5)
a=1.67m/s^2
F=ma = 45kg * 1.67m/s^2=75N
Or go straight there like this:
W=F*distance
375J=F(5m)
F=375J/5m
F=75N
Hope this helps. Thanks
Explanation:
Momentum is conserved:
m₁v₁ = m₂v₂
(42.8 kg + 31.5 kg + 25.9 kg) (19.8 m/s) = (31.5 kg + 25.9 kg) v
v = 34.6 m/s
Answer D. Metric measurement is globally considered to be superior than pounds, inches, etc.
Answer:
2m/s²
Explanation:
a = (3 - 1)/1 = 2/1 = 2m/s²
<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>
