n archer holds their bow 1.4 m above the ground, and releases an arrow at an angle of 46 egrees above the horizontal. If the arrow lands 55 m away, how fast did the arrow leave the ow string? (Units: m/s)

Please provide the correct answer

We want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.

E + N W S -S A person is rowing across the river with a velocity of 4.5 km/hr northward. The river is flowing eastward at 3.5 km/hr as shown in the image below. What is the magnitude of her velocity (v) with respect to the shore? Vriver VIOW

A throws the ball with an initial velocity V0 = 90 km / hr at an angle α with the horizontal. If the ball goes through B, Determine a) the angle α and b) the angle θ that the vector VB makes with the horizontal.

P In the movie Avengers, Hawkeye fires an arrow with a cable attached to a building after jumping from it to avoid an explosion. If he fires the arrow 5 m away and 8 m below the top of the building, with a velocity of 100 m/s and a slope of 12:5, determine the horizontal distance the arrow will travel from his initial point of firing to the point where it hits the top of the building. Prove using equations of projectile motion that the arrow will not hit the top corner of the building Please provide diagrams too, thank you
