From the first condition
1 = vo t
From the second condition
1 = 8.2 (t - 12/60)
The time it takes to travel 1 mile in the second condition is
t = 0.32 hr
The original speed is
1 = vo (0.32)
vo = 3.13 mi/h
Answer:
See below
Explanation:
Steady speed = constant slope = A
Increasing speed = increasing slope = C
B is decreasing speed
Answer:
0.6 m/s
Explanation:
The details of the masses and velocities are;
The mass of the ice skater, m₁ = 80 kg
The mass of the ball, m₂ = 8 kg
The speed with which the skater tosses the ball forward, v₂ = 6 m/s
Therefore;
According to the principle of conservation of linear momentum, we have;
m₁·v₁ = m₂·v₂
Where;
v₁ = The skater's reactive velocity
Therefore, we get;
80 kg × v₁ = 8 kg × 6 m/s
v₁ = 8 kg × 6 m/s/(80 kg) = 0.6 m/s
The skater's reactive velocity, v₁ = 0.6 m/s.
Answer:
a
past the goal post
Yes the Flyers won the match
Explanation:
Generally the distance covered by the pluck during the last 1.25 seconds is mathematically represented as
=> 
=> 
Generally the position of the puck when the game clock reaches zero is mathematically represented as
past the goal post
Given that the Bruins where one point down and Flyers scored another goal it means that the flyer are now two point up hence they won the match
The closest answer is
Alpha - mass of 4 and charge of +2; beta - no mass and charge of -1; gamma - no mass and no charge (consists of energy)
It’s not exactly correct because a beta particle has the (small) mass of an electron (also the positron). All other choices are way off, I’d go with this one.
