EXERCISE HINTS: GETTING STARTED I I'M STUCK! A catapult launches a rock at a 33° angle with respect to the horizontal. Find the maximum height attained if the speed of the rock at its highest point is 26 m/s. If you knew the vertical component of initial velocity, could you find the maximum height of the rock? Try using kinematics and projectile motion ideas to guide your thinking, then apply energy ideas to arrive at the same answer. m Need Help? Read It

You are fixing the roof of your house when a hammer breaks loose and slides down. The roof makes an angle of 45° with the horizontal, and the hammer is moving at 5.5 m/s when it reaches the edge. Assume that the hammer is moving from the top of the roof to its right edge. Part A What is the horizontal component of the hammer's velocity just as it leaves the roof? Express your answer with the appropriate units. Enter positive value if the x-component of the velocity is to the right and negative value if the x-component of the velocity is to the left. V x = Submit Part B Vy = μÅ Submit Value Request Answer What is the vertical component of the hammer's velocity just as it leaves the roof? Express your answer with the appropriate units. Enter positive value if the direction of the y-component of the velocity is upward and negative value if the y-component of the velocity is downward. O μA Value Units Request Answer ? Units ?

Can you solve the problems and show steps? Thanks.

Prove that launching a projectile at 45° provides the largest range. a. Write the range as a function of O. b. Take the derivative of the range with respect to and find the maximum angle.

Flight of a golf ball A golf ball is driven down a horizontal fairway withan initial speed of 55 m/s at an initial angle of 25° (from a tee with negligible height). Neglect all forces except gravity, and assume the ball’s trajectory lies in a plane.a. When the ball first touches the ground, how far has it traveled horizontally and how long has it been in the air?b. What is the maximum height of the ball?c. At what angles should the ball be hit to reach a green that is 300 m from the tee?

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 4.0 ss for the dart to land back at the barrel.     Part A What is the maximum horizontal range of your gun?

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.
