Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.
×
Downward force = 4.9 N
Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;
<em>Acceleration = 16.8 </em><em />
Therefore, the acceleration of the ball is 16.8

Answer:
Final velocity = 7.677 m/s
KE before crash = 202300 J
KE after crash = 182,702.62 J
Explanation:
We are given;
m1 = 1400 kg
m2 = 4700 kg
u1 = 17 m/s
u2 = 0 m/s
Using formula for inelastic collision, we have;
m1•u1 + m2•u2 = (m1 + m2)v
Where v is final velocity after collision.
Plugging in the relevant values;
(1400 × 17) + (4700 × 0) = (1400 + 1700)v
23800 = 3100v
v = 23800/3100
v = 7.677 m/s
Kinetic energy before crash = ½ × 1400 × 17² = 202300 J
Kinetic energy after crash = ½(1400 + 1700) × 7.677² = 182,702.62 J
Answer:
44 1/3 cm
Explanation:
The cube has an edge length of ∛0.027 m = 0.3 m, so a center of mass (CoM) 15 cm above the floor.
The sphere's center of mass is 40 cm above the top of the cube, so is 70 cm above the floor. The weighted average of the CoM locations is ...
((15 cm)(0.700 kg) +(70 cm)(0.800 kg))/(0.700 kg +0.800 kg)
= (10.5 kg·cm +56 kg·cm)/(1.500 kg) = 44.333... cm
The center of mass of the two-object system is 44 1/3 cm above the floor.
Answer:
No.
Explanation:
No, increasing the frequency of a wave will not increase it's wavelength. Rather it will decrease the wavelength because frequency and wavelength are inversely related.
According to Formula:
v = f(lemda)
If the speed is kept constant to find the relationship between f and wavelength.
=> f is inversely propotional to wavelength.
Hope this helps!
Have a great day!
You are probably talking about plants. They don't have the strength to move because they are stuck on the ground.
