Answer :
(a) The initial velocity is, 14.8 m/s
(b) The acceleration is, 
Explanation :
By the 1st equation of motion,
...........(1)
where,
v = final velocity = 0 s
u = initial velocity
t = time = 6.35 s
a = acceleration
The equation 1 will be:
..........(2)
By the 2nd equation of motion,
...........(3)
where,
s = distance = 47 m
Now substitute equation 2 in 3, we get:
By solving the term, we get:
The acceleration is,
Now we have to calculate the initial velocity.
Using equation 2, we gte:
The initial velocity is, 14.8 m/s
Answer:
0.303s
Explanation:
horizontal distance travel = 2.050 m, vertical distance travel = 0.45 m
Using equation of linear motion
Sy = Uy t + 1/2 gt² Uy is the inital vertical component of the velocity, t is the time taken for the vertical motion in seconds, and S is the vertical distance traveled, taken downward vertical motion as negative
-0.45 = 0 - 0.5 × 9.81×t²
0.45 / (0.5 × 9.81) = t²
t = √0.0917 = 0.303 s
Answer:
The angle of deflection will be "1.07 × 10⁻⁷°".
Explanation:
The given values are:
Mass of a cow,
m = 1100 kg
Mass of bob,
mb = 1 kg
The total distance between a cow and bob will be,
d = 2 m
Let,
The tension be "t".
The angle with the verticles be "
".
Now,
Vertically equating forces
⇒ 
...(equation 1)
Horizontally equating forces
⇒ 
...(equation 2)
From equation 1 and equation 2, we get
⇒ 
O putting the estimated values, will be
⇒ 
⇒ 
Answer:
Without the powers of the Flash, no. ... This would allow the Flash to force his molecules through the object he wants to phase through by moving them through the gaps in the object's atoms. It would probably cause more damage to the body or the object being phased through than shown in the comics/show, but it can be done.
