Chapter 11.2, Problem 37E

A particle moves to the left of the parabola. r=4/(1+cos theta) with constant speed of 4 ft/s. when theta=pie/2 Determine the radial component of the velocity and transverse component velocity.

A ball is thrown with an initial velocity of 70 km per second, at an angleof 35° with the horizontal. Find the vertical and horizontal componentsof the velocity.

A projectile is given an initial velocity of 31.5 m/s at an angle of 51.5 degrees with respect to the horizontal. How far has it moved in the x-direction at the time when its speed in the y-direction is 10.5 m/s? A projectile is launched with an initial velocity of 27.2 m/s at 64.7 degrees with respect to the horizontal. What is the speed of the projectile 1.83 s after being launched. Assume the speed is measured in m/s.   A projectile is launched with an initial velocity of 46.8 m/s at an angle of 31.2 degrees with respect to the horizontal. In meters, what is the maximum upward displacement of the projectile?
