The illustration below shows a ball on a curved track. The ball starts with zero velocity at the top of the track. It then rolls from the top of the track to the horizontal part at the ground. Ignoring friction, its velocity just at the moment it reaches the ground is 15 m/s. What is the height, h, from the ground to the top of the track? _m

A ball is suspended from a light 1.5 m string as shown. The string makes an angle of 24 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1 m/s. a) What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? b)What will be the maximum angle, in degrees, the string will make with the vertical?
A jogger runs along the dike with a speed of 4.2 m/s in a direction 30 degrees above the x-axis. What is the y component of the jogger's velocity? Give your answer to one decimal place.
Recall that the Range equation gives the horizontal distance a projectile can be launched. Suppose there is a slight breeze so that the range equation is modified in the following way: R(0) : = sin(20) – 0.900 R Part A Use Calculus to determine the angle (in degrees) at which the projectile will reach its maximum range. ?

Figure Q2(a) Profile of roller coaster: (a) The height of first hill height 20m, (b) Shape of the first hill and radius at the bottom ρ = 60 m, (c) The exit path height 5m, and (d) The loop to end the ride is a level ground, ignore the small height. Assuming a total mass of 1000kg, explain with calculations how would you design the roller coaster from start till the end of coaster ride: (i) the power of the electric motor to pull the coaster up the first hill.
A child rolls a ball on a level floor 4.1 m to another child. Part A If the ball makes 7.0 revolutions, what is its diameter? Express your answer to two significant figures and include the appropriate units. d = ________
A record is played by spinning the record so that a circular groove in the vinyl slides under the stylus. Suppose that a record turns at a rate of 33 1/3 rev. min, the groove being played is at a radius of 10.0 cm and the bumps in the grove are uniformly separated by 1.75 mm. At what rate (hits per second) do the bumps hit the stylus? Enter units as hertz (Hz). You will need v=rω ω is in rad/s and 1rev = 2 pi rad.

I already asked this question and got an answer, but I don't understand in the solution the steps to get to the answer. So, here goes the question again. While walking along a solid ground your speed is v. If your speed becomes v/2 relative to the ground while walking forward over a movable platform, the platform moves with speed ____________ and direction __________. Give speed (in terms of v) and direction (forward or backward) in the blanks.
