Select a new problem set. A 5.3 kg mass and a 9.8 kg mass are tied to a light string and hung over a frictionless pulley. How fast is the heavier mass falling 0.91 seconds after they are released from rest? m/s A lady pulls a cart with a force of 83 N. Neglecting friction, if the cart changes from resting to a speed of 0.2 m/s in a distance of 0.0101 m, what is the total mass of the cart? kg A man is pulling a cart (total 5.9 kg) with a force of 822 N. Neglecting friction, how much time does it take to get the cart from rest up to 0.5 m/s? s A lady pulls a cart with a force of 1999 N. Neglecting friction, if the cart changes from resting to a speed of 1.9 m/s in a distance of 0.06375 m, what is the total mass of the cart? kg A 9.1 kg mass and a 10.6 kg mass are tied to a light string and hung over a frictionless pulley. What is their acceleration? m/s2 A lady is pulling a cart (total 76 kg) with a force of 264 N. Neglecting friction, what is the acceleration of the cart? m/s2
