Hockey Sticks Height
10 kg go-cart is moving at a speed of 3 m / s. what is kinetic energy?
Please see Form 2. if an engine must do 500 joules of work to pull a load of 10 kg to a height of 4 meters, which is the engine performance? Please see the formula March 1 player uses a hockey stick to increase the speed of a hockey puck of 0.200 kg per 6 m / s in 2 seconds. how much force is exerted by the disc the hockey stick? 4 of 500 kg truck moving at 30 m / s hits a car parked 300 kg. which are connected together and move foward. What is the speed cars and trucks moving forward (one line) after the collision? Please see the formula
KE ^ = 1 / 2 mass x velocity x 2 = 2.1 x 10 x 3 ^ 2 = 40 joules forcexdistance work = force = 10 kg = 98.1 ug N = 4 feet of work = 4 x 98.1 = 392.4 Joules ef = 392.4/500 = 0.7848 or 78.5% Force = mass x acceleration acceleration = rate of change / hour = 6 / 2 = 0.2 kg 3m/s2 Force = x 3 m / s Momentum 2 = 0.6 N (months) = mass x speed of truck = MB 500 x 30 m = 15,000 kg / s = this is the impetus of new trucks and cars speed = 15000 x (500 300) new speed = 15000 / 800 = 18.75 m / s If you have a test tomorrow and could not make a final problem, difficulty
