From the equations of motion under constant acceleration one can derive the very handy equation for the range R of a projectile on level ground for which air resistance is negligible v sin 20 R Using g=9.8, vo = 18 m/s and 0 =45 degrees, what is the range %3D that this equation would predict for our projectile? Give your answer in units of [m] Place the target in the simulation that far from the cannon and check if our prediction agrees. You may need to zoom out to be able to move the target that far.

vo Jewell threw a ball into the air in the direction of a wall that was a distance d = 8.4 meters in front of her. The ball left her hands a distance of h 1.7 meters above the ground. The ball left her hands with an initial speed of 19 meters per second, aimed at a direction of theta = 79 degrees above horizontal. To solve this problem, let g = 9.8 meters per second squared. Ignore air resistance %3D and other sources of friction. How high above the ground (measured in meters) did the ball hit the wall?

A ground-to-ground projectile is shot with an initial velocity of 18 m/sat angle 54 degrees, measured from the horizontal. Neglecting air-resistance, what is the range of the projectile (the maximum horizontal distance in meter)?

please answer this question within 30 minutes. i will upvote. A rock is dropped into the center of a circutar pond. The ripple moved outward at 4( m)/(s). How fast does the area change, with Lespect to time, when the ripple is 3m from the center?
