PRACTICE IT Use the worked example above to help you solve this problem. A powerful grasshopper launches itself at an angle of 45° above the horizontal and rises to a maximum height of 1.04 m during the leap. (See the figure With what speed vi did it leave the ground? Neglect air resistance. X m/s EXERCISE HINTS GETTING STARTED I I'M STUCK! A catapult launches a rock at a 31° angle with respect to the horizontal. Find the maximum height attained if the speed of the rock at its highest point is 29.5 m/s X m Need Help? Read It

Explanation / Answer

Multiple questions Allowed to answer only 1 question at a time According to the chegg guidelines.

Part a) ( v * sin theta ) ^2 = 2 gh   

v^2 = 2gh / sin ^2 theta

v = sqrt ( 2 * 9.8 * 1.04 m / ( (sin 45)^2 )

v = 6.38498 m/s =======ANSWER)
