Velocity The height of a basketball thrown by Chris Paul on Neptune is given by h ( t ) = v 0 t − 5.6 t 2 meters, where t is time in seconds after he throws the ball up at v 0 m/sec 6 . a. When the ball reaches its highest point, h ′ ( t ) mustequal zero (see Exercises 95). Given a formula for the value of t when this occurs. b. How fast would he need to throw it up in order for it to reach its highest point in half a second? How high would it get?

Solution Summary: The author explains the formula for the value of t when hprime (t)=0 where height of basketball thrown by Chris Paul on Neptune is given by function.
find the zeros of the function algebraically:
f(x) = 9x2 - 3x - 2
Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach
one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck
starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a
horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate
a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The
angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude
and its direction angle from the positive x-axis.
119 lb
20.2°
