Five questions from the pack.

Q1A sprinter runs at 36 km/h. Her speed in m/s is

A. Divide km/h by 3.6: 36/3.6 = 10 m/s. Multiplying by 3.6 gives 129.6, the common inversion error. The speed is not unchanged in m/s, and 1.0 is off by a factor of ten.

Q2A projectile is launched at 40 m/s at 60 degrees above level ground. Its speed at the highest point is

B. Only the horizontal component remains at the peak: 40 cos 60 = 20 m/s. Zero is the vertical component there, 34.6 is the initial vertical component, and 40 is the launch speed.

Q3A 0.40 kg ball on a 0.80 m string moves in a horizontal circle at 4.0 m/s. The tension is

A. T = m v^2/r = 0.40 x 16/0.80 = 8.0 N. The value 2.0 N forgets to square the speed (mv/r), 6.4 N forgets to divide by the radius, and 20 N is the acceleration v^2/r with the mass left out.

Q4A spring with k = 300 N/m is stretched 0.20 m from equilibrium. The stored energy is

D. U = 1/2 k x^2 = 0.5 x 300 x 0.04 = 6.0 J. The value 12 J forgets the 1/2, 60 J mistakes the spring force kx = 60 N for an energy, and 3.0 J halves again.

Q5A crowbar has an effort arm of 1.2 m and a load arm of 0.20 m. Ideally, an effort of 50 N lifts a load of

D. Ideal MA = 1.2/0.20 = 6, so the load is 6 x 50 = 300 N. The value 8.3 N divides by the arm ratio instead of multiplying, 250 N uses a ratio of 5, and 60 N uses a ratio of 1.2.

Those are real questions from the pack, word for word.
