A projectile is launched from level ground at an angle of 30 degrees to the horizontal. If the magnitude of the launch velocity is 30 m/s, calculate the time rate of change in speed and radius of curvature when t=1, 2, and when the projectile is at its max height.
Please do the problem how the description says to do it below and put the answer neatly in a table format. Thank you.

A projectile is launched from ground level at an angle of 14.0 ° above the horizontal. It returns to ground level. To what value should the launch angle be adjusted, without changing the launch speed, so that the range doubles?
1. A projectile is launched horizontally from a height above level ground of 3 m. When it hits the ground, it's horizonta displacement from the launch point is 7 m. a. b. How much time does it spend in flight? With what speed was it launched? Suppose the projectile were now launched from the same point at an angle of 45 above the horizontal. a. b. How much time does it spend in the air? What is its horizontal displacement...
A projectile is launched straight up from ground level with an initial velocity of v0 per sec. Neglecting air resistance, its height in feet, s, after t seconds after launch is given by the equation s = –16t2 + v0t. At what time(s) will the projectile reach a height of 112 feet when v0 = 96 feet/sec? After how many seconds will it return to the ground when v0 = 96 feet/sec?
