Answer:
If two masses 5.2 kg and 4.8 kg are attached to the ends of inextensible strings passed over a frictionless pulley then the acceleration of system is 0.4 ms-2.
Explanation:
Answer:
v =4.36 m/s
Explanation:
given,
mass of object A = 18.5 Kg
initial velocity of object A = 8.15 m/s in east
mass of object B = 30.5 kg
initial velocity of object B = 5 m/s





P = 214. 45 N s
velocity after collision is equal to

v =4.36 m/s
hence, velocity after collision is equal to 4.36 m/s
Answer:
the sun's heat affects humidity of how warm the air feels to us.

Answer:
3
Explanation:
v = v⁰ (its original speed) + a (negative acceleration) X t² (time)
v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)
