Work and Power W=Fxd 1. Calculate 2. 3. 4. 5 2 3 W = F = 40 N d=4m P=W/t Energy 1. Work is measured in Joules Find the work done if the boxes move 0.5 meters. KE=mv² mv² KE= d=5m Find the work done if a force of 350 N is applied for 3 meters. W = 100 J F= m = 3 kg v=4 m/s L= 100% pull P = W = 80 J t=10 s You do 4,000 J of work in 30 seconds. What is your average power? d= Power is measured in watts P = 4000 W W = 8000 J How much work is done in 60 seconds by a 750 watt motor? W = 25 J F = 100 N KE = 3,000 J m= v= 10 m/s 1=5s P = 200 W W = KE = 18 J m=13744kg V= What is the kinetic energy of a 100 kg bear running at 3 m/s? Calculate the speed of an 80,000 kg airplane with a kinetic energy of one billion Joules. Work and Power W=Fxd 1. Calculate 2. 3. 4. 5 2 3 W = F = 40 N d=4m P=W/t Energy 1.
