Answer:
2.4m/s towards the bowling pins
Explanation:
Given parameters:
Mass of the ball = 6.6kg
Momentum of the ball = 15.9kgm/s
Unknown:
Speed of the ball = ?
Solution:
The momentum is the amount of motion a body posses;
Momentum = mas x velocity
Insert the parameters and solve;
15.9 = 6.6 x velocity
velocity = 2.4m/s towards the bowling pins
If you know the distance and the time I travelled that distance.
You just have to divide the time from the distance to get velocity
V =d

As we know,
The acceleration of mass will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
⇒ 
(a)
The mass of the block will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
(b)
The final velocity after a given time i.e.,
t = 5.00 s
⇒ 
On substituting the values, we get
⇒ 
⇒ 
In time, t = 5.00 s
The distance moved by the block will be:
⇒ 
On putting the values, we get
⇒ 
⇒ 
Answer:
weight!!!! Free fall is the motion of a body where its weight is the only force acting on an object.
