page 41, problem 51.
A vehicle changes its velocity from 90 km/h to a dead stop in 10 s. Show its acceleration in doing so is -2.5 m/s^2.
page 66, problem 44.
You push with a 20 N horizontal force on a 2 kg mass resting on a horizontal surface. The horizontal friction force is 12 N. Show that the acceleration is 4 m/s^2.
page 91, problem 43.
How many joules of potential energy does a 1.5 kg book gain when it is elevated 4 m? (Use the equation: Gravitational potential energy = weight x height. (PE = mgh) (Let g = 10 N/kg))
