Relative to an observer located at B, at what times (find two times t₁ < t₂) will the line of sight to the projectile make an angle of 25° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile.

While scrambling directly toward the sideline at a speed vQ = 18 ft/sec, the football quarterback Q throws a pass toward the stationary receiver R. At what angle α should the quarterback release the ball? The speed of the ball relative to the quarterback is 67 ft/sec. Treat the problem as two-dimensional.
A ball is thrown vertically upward with a speed (vo) of 15 m/s at an initial position of so= 10 m. The ball is subjected to a constant downward acceleration of 9.81 m/s2. Determine the maximum height, smaxreached by the ball. Determine the time of flight when it returns to its original position. Determine the time of flight when it hits the ground. Determine the velocity just before it hits the ground. Check your answer using a different equation. Plot v(t) and s(t) from t = 0 to the time when the ball hits the ground.
If a ball is dropped from a height of 5 feet, determine velocity of the ball just before impact with the ground. Let positive y be upward, so the ball will have negative velocity. Provide your answer in ft/sec, but do not include units in your submittal.
A projectile is fired vertically from point A with an initial speed of 295 ft/sec. Relative to an observer located at B, at what times (find two times t1 < t2) will the line of sight to the projectile make an angle of 35° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile. Calculate the height h when the projectile is at point C.
Car A is moving with constant speed v on the straight and level highway. The police officer in the stationary car P attempts to measure the speed v with radar. If the radar measures “line-of sight” velocity, what velocity v' will the officer observe? Evaluate your general expression for the values v = 74 mi/hr, L = 605 ft, and D = 19 ft, and draw any appropriate conclusions.
A ball roles off a table as shown in the figure below with a horizontal velocity vx=7.9 m/s. If the height of the table y=1.5 m, determine the magnitude of the total velocity when the ball hits the ground. Hint: Calculate the vx and vy then use the Pythagorean Theorem.
