Semi-conductors are occasionally conductors based on their needs. Hope this helps!!!
In an attempt to reduce our dependence on non-renewable resources, and cut down on the harm to the environment, we could burn biomass to produce electricity.
(a) The impulse delivered to the ball by the racket is 5.24 kg.m/s
(b) The work that the racket does on the ball is -35.1 Joule
<h3>Further Explanation</h3>
<u>Given :</u>
mass of ball = m = 0.06 kg
initial velocity = v₁ = -50.4 m/s
final velocity = v₂ = 37.0 m/s
<u>Unknown :</u>
(a) Impulse = I = ?
(b) Work = W = ?
<u>Solution :</u>
<h2>Question (a) :</h2>
In this question , we could use the formula from Second Law of Newton :








<h2>Question (b) :</h2>

Formula for Velocity = DISTANCE traveled/TIME to travel distance + direction
For this one, we can use mph(miles per hour) as unit.
v = 1,000 miles / 336 hours (2 weeks = 24 hours x 14 days = 336 hrs)
= 2.98 mph North
or we can use kph (kilometers per hour)
v = 1609.34 km / 336 hours (1 mile = 1.60934 km)
= 4.79 kph North
