A 5.00105 -kg rocket is accelerating straight up. Its engines produce 1.250107 N of thrust, and air resistance is 4.50106 N. What is the rocket's acceleration? Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton's laws of motion.
Consider the 65.0-kg ice skater being pushed by two others shown below. (a) Find the direction and magnitude of Ftot . the total force exerted on her by the others, given that the magnitudes F1and F2are 26.4 N and 18.6 N, respectively. (b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot ?
