Answer:
The softball hits the ground first because it is less affected by air resistance.
Explanation:
Answer
given,
mass of block (m₁)= 8 kg
mass of other block (m₂) = 5.75
velocity of first object (v₁) = 5.5 m/s
velocity of second object (v₂) = 6 m/s
a) total momentum before collision = total momentum after collision
m₂v₂ - m₁ v₁ = (m₁ + m₂) V
5.75 x 6 - 8 x 5.5 = (5.75 + 8 ) V
V = - 0.69 m/s
b) negative sign shows the direction motion of object after collision toward left.
c) Initial kinetic energy
K_i = 224.5 J
final kinetic energy
=
=
K_f = 3.23 J
loss in mechanical energy
Δ KE = 3.23 - 224.5
Δ KE = -218.1 J
negative sign shows loss of mechanical energy.
Answer:
the answer is 4m/ s²

I think it’s B, conduction.
Answer:
speed of ball B is 0.5 m/s
Explanation:
First the angle at which it's invliy does not matter.
Initial momentum is equall to final momentum.
M1v1 + m2v1 = m1v2 + m2v2
0.17*4 + ( 0.17*0) = 0.17*3.5 + 0.17v2
0.68 + 0= 0.595 + 0.17v2
0.68-0.595= 0.17v2
0.085 = 0.17v2
0.5 = v2
V2 = 0.5 m/s
