Question 9

If the fifth we’re attempted using a bullet of mass 30g, the experimentalists could expect the block to swing up to the height of:

Answer 9

Answer: 170cm

The data in the table suggests that the height h is approximately proportional to m^2. Going from trial 1 to trial to m increases by a factor of 2 and h increases by a factor of 2^2= 4. From trial 1 to trial 3, increases by almost a factor of 3^2=9. If m increases by a factor of 3 (m=10g to m=30g), then h should increase almost by a factor of 3^2=9, to (20cm) * 9= 180cm
