Given:
= 12 m/s
Time = 15 s
To find:
Deceleration = ?
Formula used:
Deceleration is given by,
a = 
Solution:
Acceleration of the body is rate of increase of velocity. Deceleration of the body is negative acceleration i. e rate of decrease of velocity.
Thus, deceleration of the body is given by,
a =
where a is the deceleration of the body
v is the velocity
is rate of change of velocity
t is the time
a = 
a = 0.8 m/ 
Thus, deceleration is 0.8 m/ .
The bowling ball would have the most inertia because it has the most mass. Inertia is the ability to resist a change in motion. So, it sort of makes sense that the more massive an object, the more resistance it has against outside forces.
Bowling ball would be your answer since it has the most mass.
<h3><u>Answer</u>;</h3>
$347.22
<h3><u>Explanation</u>;</h3>
Principal = $14,200
Rate = 8.5%
Time = 105 days = 105/365
Interest = Principal x Rate x Time
Interest = 14,200 x 0.085 x 105/365
Interest = 347.219
= $347.22
Conservation of momentum: total momentum before = total momentum after
Momentum = mass x velocity
So before the collision:
4kg x 8m/s = 32
1kg x 0m/s = 0
32+0=32
Therefore after the collision
4kg x 4.8m/s = 19.2
1kg x βm/s = β
19.2 + β = 32
Therefore β = 12.8 m/s
Gravitational potential energy is energy.
The unit of energy is the Joule.
1 Joule = 1 kilogram-meter² / sec²
