Step by step solution

01

Given information

We are given with the equations:

vx=-(6cos45°)m/s+3m/svy=(6sin45°)m/s+0m/svyt1=100mx1=vxt1

a. We have to write a realistic problem for which these are the correct equations.

b. Finish the solution of the problem, including a pictorial representation.

02

Part a) Step 1: Realistic Problem  

A stone is thrown at an angle from a moving boat is45°. Initially the velocity is 6m/sand the horizontal initial velocity is 3m/s. Calculate the time and the distance traveled by the stone in water?

03

Part b) Step 1: Calculation

From first equation we get:

vx=-(6cos45°)m/s+3m/svx=-4.24m/s+3m/svx=-1.24m/s

From the second equation:

vy=(6sin45°)m/s+0m/svy=4.24m/s

From third one:

vyt1=100m4.24m/s×t1=100t1=23.57s

From last one equation:

localid="1648127870472" x1=vxt1x1=-1.24m/s×23.57sx1=-30m

Negative sign show that the car travels along west.

Part b) Step 2: Pictorial representation 

The Pictorial representation of the given equations are as:

A cart that is rolling at constant velocity on a level table fires a ball straight up.

a. When the ball comes back down, will it land in front of the launching tube, behind the launching tube, or directly in the tube? Explain.

b. Will your answer change if the cart is accelerating in the forward direction? If so, how?

For a projectile, which of the following quantities are constant during the flight: x,y,r,vx,vy,v,ax,ay? Which of these quantities are zero throughout the flight?

An electromagnet on the ceiling of an airplane holds a steel ball. When a button is pushed, the magnet releases the ball. The experiment is first done while the plane is parked on the ground, and the point where the ball hits the floor is marked with an X. Then the experiment is repeated while the plane is flying level at a steady 500mph. Does the ball land slightly in front of the X (toward the nose of the plane), on the X, or slightly behind the X(toward the tail of the plane)? Explain.

A tennis player hits a ball 2.0 m above the ground. The ball

leaves his racquet with a speed of 20.0 m/s at an angle 5.0° above the horizontal. The horizontal distance to the net is 7.0 m, and the net is 1.0 m high. Does the ball clear the net? If so, by how much? If not, by how much does it miss?

The radius of the earth's very nearly circular orbit around the sun is 1.5×1011m. Find the magnitude of the earth's (a) velocity, (b) angular velocity, and (c) centripetal acceleration as it travels around the sun. Assume a year of 365 days.
