Answer:
The velocity of the ball when its hit the ground will be 54.22 m/sec
Explanation:
We have given height from which ball is dropped h = 150 m
Acceleration due to gravity
As the ball is dropped so initial velocity will be zero so u = 0 m/sec
According to third equation of motion we know that
So the velocity of the ball when its hit the ground will be 54.22 m/sec
Answer:
The required IVP is;
u'' + 196u = 0
where;
u(0) = 0 and
u'(0) = -10
Explanation:
See the attached for explanation
Answer:
0.5 second
Explanation:
We are given that
Force, F=20 N
Mass, m=5 kg
Change in velocity,=2m/s
We have to find the time taken to change the velocity .
We know that
Force, F=ma
Where
Acceleration, a=Change in velocity/time
Substitute the values
