In a physics lab experiment, a spring clamped to the table shoots a 20 g ball horizontally. When the spring is compressed 20 cm, the ball travels horizontally 7.3 m and lands on the floor 1.5 m below the point at which it left the spring. What is the spring constant in N/m. (Don't forget to convert units.) Hint: This is a projectile motion problem. Use time to fall t = srt(2*y/g).
Projectile
A projectile is an object that is thrown without any fuel. A projectile is generally thrown with a velocity making an angle with respect to the horizontal. Examples of a projectile are meteors falling from the sky and an artillery gun firing at enemy positions.

- A child throws a stone downward from the top of a cliff with a speed of 4m/s. You notice that it took 2 seconds for the stone to hit the ground. What is the height of the cliff? (Start with a function for the acceleration using g ≈ 9.8m/s2 .An engineer is testing how quickly a car accelerates from rest. The velocity V is measured in miles per hour, as a function of time t, in seconds, since the car is at rest. See the table below. What is the slope for the linear function modeling velocity as a function of time, V=, and what would the formula be for the velocity at time 0, V(0) Time (t) Velocity (V) 2.0 28.9 2.5 35.0 3.0 41.1 3.5 47.2A particle starts from the origin at t = 0 with a velocity of (16 - 12) m/s and moves in the xy plane with a constant acceleration of = (3.0 - 6.0) m/s2. What is the speed of the particle at t = 2s?
- help answer please.Needs Complete solution with 100 % accuracy don't use chat gpt or ai plz plz plz plz.The velocity of a particle is given by v = 29t²-88t - 196, where v is in feet per second and t is in seconds. Plot the velocity v and acceleration a versus time for the first 4 seconds of motion. After you have the plots, answer the questions as a check on your work. -1 Questions: + 0 + 1 When t = 0.5 sec, V = 2 i When t = 3.3 sec, V = i + 3 +s, ft or m When the acceleration is zero, the velocity is i ft/sec, a = ft/sec, a = i i ft/sec. ft/sec² ft/sec²
