The longest recorded pass in an NFL game traveled 83 yards in the air from the quarterback to the receiver. Assuming that the pass was thrown at the optimal 45° angle, what was the speed at which the ball left the quarterback’s hand?

A soccer player kicks a ball at an angle of 62° from the horizontal with an initial speed of 26 m/s. (a)  Find the horizontal component of the ball’s velocity.  (b)  Find the vertical component of the ball’s velocity.  (c)  How high does the kicked ball rise before it starts to come down? (d)  How long does the ball stay in the air?  (e) How far downfield does the ball land?  can you please help me with (d) and (e)?

A projectile launched at 45° upwards from the ground takes 2.4 seconds to return to the ground. Approximately what speed was the projectile launched?

Tolerance is -+1 to the 3rd significant digit

a) If Billy-Joe kicks a stone with a horizontal velocity of 3.50 m/s, and it lands in the water a horizontal distance of 5.40 m from where Billy-Joe is standing, what is the height of the bridge? b) If the stone had been kicked harder, how would this affect the time it would take to fall?

A catfish is spotted at the bottom of a creek. The depth of the water is 2 m. A hunter (with no knowledge ofoptics) fires a rifle shot, directly aimed at the catfish. The bullet strikes the water at an angle of 40° to the water. Assumethat the bullet is not deflected by the air/water interface, what is the distance from the bullet hole at the bottom of the creekto the catfish?A) 0.88 mB) 0.97 mC) 0.49 mD) 0.56 mE) 0.73 m

A juggler throws balls straight up in the air. After the balls leave his hand and while it is in the air, explain WHY each of the following four statement is FALSE. Write the right answer. (a) The velocity of the ball is always in the same direction as it's acceleration. (b) The velocity of the ball is never in the same direction as it's acceleration. (c) The acceleration of the ball is zero. (d) The velocity of the pin is the same direction as it's acceleration on the way up.

As a projectile moves in its path, is there any point along the path where the velocity and acceleration vectors are parallel to each other? ( assume the object is thrown upward and forward, but not straight up.)

Use a graphing utility to obtain the path of a projectile launched from the ground (h = 0) at the specified values of θ = 35°, v0 = 300 feet per second. In the exercise, use the graph to determine the maximum height and the time at which the projectile reaches its maximum height. Also use the graph to determine the range of the projectile and the time it hits the ground. Round all answers to the nearest tenth.

A baseball is hit with an initial speed of 45 m/s at an angle of 33° relative to the x (horizontal) axis. (a) Find the speed of the ball at t = 3.0 s. m/s (b) What angle does make with the x axis at this moment? ° (counterclockwise from the +x-axis) (c) While the ball is in the air, at what value of t is the speed the smallest?
