Luyando wants to have a bit of fun with her wagon. She puts her 12 π‘˜π‘” baby sister, Waluse, on the wagon and pulls it across the floor using a rope at an angle of 22Β° above the floor. Using the spring balance that mum uses to weigh things in the kitchen, Luyando realises that the tension in the rope is constant and has a value of about 40 𝑁. Use the work-energy theorem to find Waluse’s speed after being pulled 4.0 π‘š across the living room. The coefficient of friction is 0.2 and the weight of the wagon is 3 π‘˜π‘”.
