A ball is thrown horizontally from the top ofa building 110 m high. The ball strikes the
ground 61 m horizontally from the point of
release.
What is the speed of the ball just before it
strikes the ground?
Answer in units of m/s
Answers
The speed of the ball would be 13 m/s just before it strikes the ground.
A ball is thrown horizontally from the top of a 110 m high building. 61 meters horizontally from the moment of release, the ball falls on the earth.
What is the velocity?
Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
First of all, we get the time of aviation from the vertical component:
Here s = 110 m and g = 9.8 m/s²
s = 1/2 × gt²
Solve for t
t = √(2s/g)
Substitute the values of s = 110 m and g = 9.8 m/s² in the equation,
t = √(2×110/9.8)
t = √22.44
t = 4.7 sec
The horizontal component of velocity is constant :
v = s/t
Here s = 61 m and t = 4.7 sec
v = 61/4.7
v = 12.97 ≈ 13
Therefore, the speed of the ball would be 13 m/s just before it strikes the ground.

Step-by-step explanation:
prime factors of 20 = 2 * 2 * 5
Final answer:
The denominator of the fraction 7/20 can be written as the product of prime factors: 2 x 2 x 5.
Explanation:
The denominator of the fraction 7/20 can be written as the product of prime factors by finding the prime factorization of 20.
- Start by dividing 20 by the smallest prime number, which is 2. 20/2 = 10.
- 2 is a prime factor, so we continue to divide 10 by 2. 10/2 = 5.
- 5 is a prime number, so we have found the prime factorization of 20: 2 x 2 x 5 = 20.
Therefore, the denominator of the fraction 7/20 can be written as 2 x 2 x 5.

Standard form = 94,237,108.
Step-by-step explanation:
Given : 94 million,237 thousand ,108
To find : Write is in Standard form .
Solution : We have given 94 million,237 thousand ,108
94 million = 94, 000,000.
237 thousand = 237, 000.
108.
Standard form = 94,000,000+237,000+108.
Standard form = 94,237,108.
Therefore, Standard form = 94,237,108.
94= Millions
237= Thousands
108= Hundreds

What is m angle BCP
Answers
Answer:
Measure of ∠BCP is 36°
Step-by-step explanation:
Given the circle in which measure of arc BC is 72°
we have to find the measure of angle BCP.
m∠BOC=∠2=72°
By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.
∴ ∠2=2∠1 ⇒ 72=2∠1
⇒ ∠1=36°
By alternate segment theorem which states that
The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.
⇒ ∠3=∠1=36°
Hence, measure of ∠BCP is 36°
