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.
Explanation:
work input is the work done by the machine in lifting the drum = Force × distance
100N × 10m
= 1000 J
The answer is most likely Kelvin
<h3>
Given</h3>
- mass = 200kg
- acceleration = 10m\s^2
Star coding
<h3>
As we know that force = mass × acceleration</h3>
- F = m×a
- F = 200 ×10
- F = 2000N
<h3>
so mate here is ur ans force is equal to 2000N.</h3>
Hope it helps
Answer:
Distance, S = 110 meters
Explanation:
Given the following data;
Initial velocity = 15 m/s
Acceleration = 4 m/s²
Time = 5 seconds
To find the distance covered, we would use the second equation of motion;
Where;
S is the distance covered or displacement of an object.
u is the initial velocity.
a is the acceleration.
t is the time.
Substituting the values into the equation, we have;
Distance, S = 110 meters
