Answer:
- Mass of the ball = 45 Kg
Explanation:
velocity attained by the ball:
Distance/time= 54/9 = 6m/s (meter per sec)
As work done on ball = distance * force applied
= 54*15
= 810 J ----------------- (i)
acc. to the conservation of energy:
work done = kinetic energy + potential energy
= 1/2*m* + 0(as object is on ground)
= 1/2*m*
= 1/2*36*m
= 18*m ------------------- (ii)
∵,(i) =(ii)
18*m = 810
m=810/18
m= 45kg
