In tests on earth a lunar surface exploration vehicle (mass = 5.45 × 103 kg) achieves a forward acceleration of 0.217 m/s2. To achieve this same acceleration on the moon, the vehicle's engines must produce a drive force of 1.50 × 103 N. What is the magnitude of the frictional force that acts on the vehicle on the moon?

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

Can you match these to the correct definition
