Answer:
7.75m/s or 
Explanation:
m = 1.5kg
u= 10m/s
s = 2m
a = 
v = ?
acceleration due to gravity is negative when an object is going up because the force of gravity reduces the speed of the object
using the formula ;
since the object is moving upwards (negative acceleration)
= 100 - 2(10)(2)
100 - 40
= 60
v = 
= 7.75m/s
The answer to this is <span>KE = 8100 J</span>
