Explanation:
Let's solve the problem by using conservation of momentum:
m1 u1 + m2 u2 = m1 v1 + m2 v2
where:
m1 = 3.5 g is the mass of the blue marble
m2= 1.2 g is the mass of the red marble
u1 = 15 cm/s is the initial velocity of the blue marble
u2 = 3.5 cm/s is the initial velocity of the red marble
v1 = 5.5 cm/s is the final velocity of the blue marble
We can find the final velocity of the red marble by re-arranging the equation and solving for v2 :
v2 = 1/m²(m1 u1 + m2 u2 - m1 v1)=
=1/1.2(3.5×15+1.2×3.5−3.5×5.5 )=31cm/s
Answer:
A) The ball will roll forever in a straight path.
Explanation:
Given that,
The vertical motion of mass A is defined by the relation as :
At t = 1 s
x = 115.33 mm
(a) We know that,
Velocity, 
At t = 1 s
v = 18.94 mm/s
We know that,
Acceleration, 
At t = 1 s
(b) For maximum velocity, 
t = 45 seconds
For maximum acceleration, 
t = 61.8 seconds
Hence, this is the required solution.
Answer:
Potential refers to stored energy while kinetic is energy in motion. All energy, whether potential or kinetic, is measured in Joules (J).

Explanation:
Average velocity: 6.01×103 m/s.
Velocity at time t=0 s : 0 m/s.
Velocity at t=10 s : 2.40×104 m/s.
