A student on a go-cart (with a combined mass of 82 kg) moving at 6.7ms collides with a 23 kg cart initially at rest. As a result of the collision, momentum is transferred from the first cart to the second cart. The velocity of the student and cart is 4.80ms after the collision. The collision lasts for 0.13 s. What is the absolute value of the impulse that is delivered to the student and the first cart during the collision?

Aferris wheel is a vertical, circular amusement ride with radius 9 m. riders sit on seats that swivel to remain horizontal. the ferris wheel rotates at a constant rate, going around once in 9 s. consider a rider whose mass is 56 kg. at the bottom of the ride, what is the perpendicular component of the rate of change of the rider's momentum? at the bottom of the ride, what is the vector force exerted by the seat on the rider?

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
