Acceleration due to gravity on the surface of the moon is 1.63 m/s^2. What is the weight of an astronaut on the surface of the moon if he weighs 146 lbs on earth?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
