Find the horizontal and vertical components of the 100-m displacement of a superhero who flies from the top of a tall building following the path shown in Fig. P3.18.

Please do help me with this please. It is a physics question. Please, i promise to give a perfect feedback to you.

what’s the initial and final height of the ball?

A 1.00-MΩ voltmeter is placed in parallel with a 75.0-k Ω resistor in a circuit.                                                                                                            (a) Draw a circuit diagram of the connection. (b) What is the resistance of the combination?(c) If the voltage across the combination is kept the same as it was across the 75.0-k Ω resistor alone, what is the percent increase in current?(d) If the current through the combination is kept the same as it was through the 75.0-k Ω resistor alone, what is the percentage decrease in voltage? (e) Are the changes found in parts (c) and (d) significant? Discuss.

You hit a golf ball from the (level) ground, with an initial speed and an initial angle.  Ignore air resistance.  (This is very unrealistic.) The initial speed is v0 = 23.7 m/s, and the angle the ball is hit at is θ = 46o.  Calculate vx0, the initial horizontal component of velocity (in m/s). What equations describe the trajectory of the golf ball?

3. 15. A skateboarder shoots off a ramp with a velocity of 6.6 m/s, directed at an angle of 58° above the horizontal. The end of the ramp is 1.2 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?

Rain is falling steadily, but there is no wind. You are on a bus that moves at 35.0 km/hr, and you see that the rain appears to be falling at an angle of 42o with respect to the vertical. What is the vertical speed of the rain drops?

A landscape architect is planning an artificial waterfall in a city park.Water flowing at 0.750 m/s leaves the end of a horizontal channel at the top of a vertical wall h = 2.35 m high and falls into a pool (Fig. P3.70). (a) How far from the wall will the water land? Will the space behind the waterfall be wideenough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-twelfth actual size. How fast should the water flow in the channel in the model?

I am again standing on the sky scraper building of height 45.0 m. I throw a metal ball from the top of the building at an angle of 30.00  above the horizontal surface. The ball lands 75 cm from the base of the building.  (a) What is the time taken by the ball to reach the ground? (b) How high from the ground the ball can reach?

A GPS tracking device is placed in a police dog to monitor its whereabouts relative to the police station. At time t₁ = 23 min, the dog's displacement from the station is 1.2 km, 33° north of east. At time t₂ = 57 min, the dog's displacement from the station is 2.0 km, 75° north of east. Find the magnitude and direction of the dog's average velocity between these two times. 1.4 m/s, 31° west of north 0.80 m/s, 42° west of north 1.6 m/s, 42° north of east 0.52 m/s, 88° north of east 0.67 m/s, 21° west of north
