Answer:
Work done is 93.75J
Explanation:
Given mass, m = 30kg; Time = 5 seconds; force = 15N; u= 0
Acceleration, a = F/m ⇒ 15/30
⇒ 0.5ms
Displacement , s= ut+1/2at²
⇒ 0 +1/2 (0.5*5*5)
⇒ 0 + 1/2(0.5*25)
⇒ 0 + 1/2(12.5)
⇒ 0 + 6.25
⇒ 6.25m
work done = Fs=15*6.25= 93.75 J
The order goes like this:
Radio, Micro waves, Infrared, Visible, UV (Ultra Violet), X-Ray, Gamma Ray.
They would hit the ground at the same time. No matter the weight laws of physics.
