A student on a go-cart (with a combined mass of 85 kg) moving at 6.2 m/s collides with a 15 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 5.06 m/s after the collision. The collision lasts for 0.05 s. What is the absolute value of the force that acts during this collision

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
