A 90. 0-kg ice hockey player hits a 0. 150-kg puck, giving the puck a velocity of 45. 0 m/s. If both are initially at rest and i

f the ice is frictionless, how far does the player recoil in the time it takes the puck to reach the goal 15. 0 m away?.

The distance traveled by the hockey player is 0.025 m.

<h3>The principle of conservation of linear momentum;</h3>
  • The principle of conservation of linear momentum states that, the total momentum of an isolated system is always conserved.

The final velocity of the hockey play is calculated by applying the principle of conservation of linear momentum;

m_1v_1 = m_2 v_2\\\\v_1 = \frac{m_2 v_2}{m_1} \\\\v_1 = \frac{0.150 \times 45}{90} \\\\v_1 = 0.075 \ m/s

The time taken for the puck to reach 15 m is calculated as follows;

t = \frac{d}{v} \\\\t = \frac{15\ m}{45 \ m/s} \\\\t = 0.33 \ s

The distance traveled by the hockey player at the calculated time is;

d = vt\\\\d = 0.075 \ m/s \ \times 0.33 \ s\\\\d = 0.025 \ m

Answer:

86400 \div 86400 \\ 1

86400 seconds is 1 day

Explanation:

There is 86400 seconds in 1 day so you divide the seconds by 86400 to get the day.

Suppose that a wave forms in shallow water. Then the depth d of the water (in meters) and the velocity v of the wave (in meters
ziro4ka [17]

Explanation:

The depth d of the water (in meters) and the velocity v of the wave (in meters per second) are related by the equation as:

v=9.8d

We need to find the water's depth is a a wave formed in shallow water has a velocity of 4.5 m/s.

So,

d=\dfrac{v}{9.8}\\\\d=\dfrac{4.5}{9.8}\\\\d=0.459\ m

Hence, if the wave formed in shallow water has a velocity of 4.5 m/s, then the water's depth is 0.459 m.
