Question

Table 3. Effect of 10% increases in the speed, angle, and height of release on a projectile's flight.

	Projection				Flight Results
	speed	angle	height		vxi (m/s)	vyi (m/s)	ttot (s)	dx (m)
Nominal	10 m/s	38 º	2.0 m		7.88	6.16	1.52	12.00
+10% speed	11 m/s	38 º	2.0 m		8.67	6.77	1.63	14.14
+10% angle	10 m/s	41.8 º	2.0 m		7.45	6.67	1.61	12.02
+10% height	10 m/s	38 º	2.2 m		7.88	6.16	1.52	12.00

Look carefully at the vertical speed, horizontal speed, and total time of flight changes that occurred in Table 3. Are these changes as you would expect? Describe and explain.
