Charlie kicks a soccer ball up a small incline. On the way up, ball’s acceleration has magnitude |a| = 0.45 m/s2 and is directed in downhill direction. Charlie kicks the ball at the bottom of the incline and then immediately start to walk up the incline with constant speed. Charlie performs twi different trials. a) In the first trial, Charlie kicks the ball with initial speed v0 = 3.4 m/s. Charlie is 2.3-m behind the ball when the ball is at the highest point. What is the speed vC of Charlie? b) Charlie performs the second trial. He kicks the ball with unknown speed v 0 0 but walks with the same speed vC as in the first trial. Charlie is now 0.8 m behind the ball when the ball is at the highest point. What is the initial speed v 0 0 of the ball at the bottom of the hill? (Hint: You need to set-up a quadratic equation for v 0 0 ).

1.A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.70 × 10-3 s, and the force of the kick is given by F(t) = [(6.56 × 105)t - (3.86 × 108)t2] N for 0≤t≤1.70×10-3s, where t is in seconds. Find the magnitudes of the following: (a) the impulse on the ball due to the kick, (b) the average force on the ball from...

A soccer player kicks the ball toward a goal that is 27.6 m in front of him. The ball leaves his foot at a speed of 18.5 m/s and an angle of 31.2° above the ground. Find the speed of the ball when the goalie catches it in front of the net. (Note: The answer is not 18.5 m/s.) I keep getting a final velocity of 13.92797m/s but its incorrect. Please show your work so I can see what I'm...

1. A soccer player will kick a ball 80 times during practice. Assume that the kicks are independent of each other, and the probability that he scores is 0.6 (60% chance that the ball goes into the goalpost and 40% chance that the ball does not go into the goalpost). Let X be the number of successful goals (number of scores) out of the 80 kicks. (a) What is the distribution of X? (b) Write the pmf f(x) and name...

You are kicking a soccer ball on a windy night. The acceleration of the wind in the x direction is 2.0 m/s. a) When the ball is kicked into the wind (de-accelerated) at the angle pi/2, and initial velocity 40 m/s, how far does the ball travel in the x direction prior to landing? b) When the ball is kicked with the wind (accelerated), at the same angle and initial velocity, how far does the ball travel in the x...

1. Ball rolling down an incline :Later you will be measuring the acceleration of the rolling ball down the incline for several different incline angles, and we want to compare with the theoretical expected value. The best way to show this is to plot the acceleration on the vertical axis, and the value of sin(θ) on the horizontal axis, as shown on the plot below. Draw in the expected theoretical variation of the acceleration on this plot. 2. A 0.200...
