A football player releases a ball with the initial conditions shown in the figure. Determine the radius of curvature of the trajectory (a) just after release and (b) at the apex. For each case, compute the time rate of change of the speed. vo = 80 f/sec - 35

110 Determine the distance s at which a ball thrown with a velocity vo of 100 ft per sec at an angle 0 = tan-1 will strike the incline shown in Fig. P-1109. 1110. In Fig. P-1109, a ball thrown down the incline strikes it at a distance s =254.5 ft. If the ball rises to a maximum height h = 64.4 ft above the point of release, compute its initial velocity v. and inclination 0. Ana. FIG. P-1109 and P-1110. v.-80.5 ft per sec; 0 =53.1°

A basketball player tosses a basketball with an initial velocity of v at an angle of 35 degrees, and in the position shown below. The basketball then travels the dashed arc and goes into the basket (i.e. hits a point 11 meters away horizontally and 3 meters off the floor vertically). 2 m Vo 35° 11 m 3 m a) What is the magnitude of the initial velocity of the basketball? b) When does the basketball go into the basket? c) How fast is the basketball travelling when it makes the basket? d) What is the maximum acceleration of the basketball during its flight?

5. A projectile is shot off a 200 m cliff at a 45° angle to the ground with an initial speed of 120. Calculate a) the final distance of the projectile from the base of the cliff and b) the time it takes for the projectile to reach the ground.

Darshan kicks the ball in a parabolic path. The ball leavesthe player’s foot with a speed of 20 m/s, making an angle of40o with the horizontal. a) Calculate the maximum height of its trajectory [2]b) Determine its velocity as it hits the ground again. Air resistance is negligible.c) How far from Darshan does the soccer ball land?

Air resistance is negligible. c) How far from Darshan does the soccer ball land?

1. Suppose you take a ball to the top of a building that is 12.0 m high, and the horizontal distance where the ball lands is 4.5m from the launch point. If the basketball is thrown horizontally, (a) What is the initial launch speed, vox, needed to hit the ground? What are the (b) the vertical and horizontal velocity components of the ball just before it hits the ground, and (c) what are the magnitude and direction at this point. (d) What are the velocity components, vx at half the time? (e) What are the balls vertical and horizontal position at & Vy, this time? Draw all velocity vectors and 0 and the resultant vector v and label. Sketch and Label all velocity vectors for (b) to (e) Define the coordinate axis for each mass.
