Answer: 1.6m/s
Explanation:
M1 = 13500kg
U1 = 4.5m/s
M2 = 25000kg
U2 = 0m/s (since the body is at rest)
V = ? (Common velocity or velocity after impact)
M1U1 + M2U2 = (M1 + M2)V
But U2 = 0
M1U1 = (M1 + M2)V
13500 * 4.5 = (13500 + 25000)v
60750 = 38500v
V = 60750 / 38500 = 1.5779 = 1.6m/s
Maybe sea or onshore breeze
It develops due to the difference of air pressure greater by the different temperature of the water and land
Speed = 500m/5min = 100 m/min. Direction = west. Velocity = 100 m/min west.
Answer:
I think that's Newton's second law of motion
Explanation:
f = m(v-u)
________
t
since a = (v-u)t
f = ma
