Answer:
Option (D) is correct.
Explanation:
The balloon lands horizontally at a distance of 420 m from a point where it as released.
Velocity of air balloon along +X axis =10 m/s
velocity of ball=4 m/s along + X axis
the velocity of balloon gets added to the velocity of ball. So the resultant velocity of the balloon=10+4 = 14 m/s
time taken= 30 s
The distance traveled is given by d= v t
d= 14 (30)
d= 420 m
Thus the balloon lands horizontally at a distance of 420 m from a point where it as released.
What statement best describes what it means to maximize your efforts in sports?
D.none of the above
K.E= 50,000 Joules= 1/2mv^2=1/2x1,000kgxv^2
v^2=2x50,000 Joules/1,000kg = 100m^2/v62
v=10m/s
The speed of the car is 10 m/s
