Andre hit a golf ball from the ground and its movement follows the equation hbracket(t)=-16sup(t,2)+44t, where t is the time in
seconds, and hbracket(t) is the height of the ball at a given time t. Find the time that it took the golf ball to hit the ground again correct to two decimal places.
Answer: the golf ball with hit the ground again after 2.75 seconds
Step-by-step explanation:
The movement of the golf ball from the ground follows the equation h(t)=-16t^2+44t,
where t is the time in seconds, and h(t) is the height of the ball at a given time t
By the time the golf ball hit the ground, the height from the ground would be zero. This means that we would equate the quadratic equation to zero. It becomes
First find angle EBC. The are for a triangle is 180 degrees. It is a right triangle and has a right angle. 180 - (90 + 50) 180 - 140 angle EBC IS 40 NOW FIND X The line is 180 degrees. 180 -40 = 140 X = 140 DEGREES
