1. A golf ball is launched from the ground level at an angle of 50^o and with an initial velocity of v_o = 54 m/s. What is the time of flight, t, of the ball (i.e., total time that the ball is in the air)? Ignore the effect of air resistance. Please round your answer to one decimal place.

2. A football is kicked from the ground level at an angle of 35^o and with an initial velocity of 27 m/s. How high (in meters) does the ball reach in t = 1.69 s? Please round your answer to one decimal place.

3. A ball is launched as a projectile at an angle of 46^o. The initial velocity of the ball is 31 m/s. What is the maximum horizontal distance, in meters, that the ball reaches? Take the acceleration due to gravity, , to be 9.80 m/s². Please round your answer to the nearest whole number.

4. A projectile is launched from the ground level at an angle of 61^o and with an initial velocity of 26 m/s. What is the vertical component of the projectile's velocity at t = 1.31 s? Please note that your answer may be negative. If this is the case, put the negative answer in the box. Please round your answer to one decimal place.
