Answer:
5m/s
Explanation:
From momentum conservation:
Momentum =mass × veloclty
Momentum before collision = momentum after collision
Given that mass of dart = 0.5kg, mass of apple = 1kg, velocity of dart = 1.5m/s, velocity of apple = 0m/s
(0.5×1.5)- (1×0) = ( 0.5+1)v
7.5-0 = 1.5v
7.5 = 1.5v
V = 7.5/1.5
V = 5m/s.
velocity of the dart and apple just after the dart is embedded is 5m/s
