A drone is being directed across a frictionless ice covered lake. The mass of the drone is 1.50 kg, and its velocity is 3.00i ^ m/s . After 10.0 s, the velocity is 9.00i ^ + 4.00j ^ m/s . If a constant force in the horizontal direction is causing this change in motion, find (a) the components of the force and (b) the magnitude of the force.
A golf ball is hit from the ground (elevation is zero) and takes off with a launch speed of 55 m/s and a launch angle of 25 degrees. The acceleration due to gravity g = 9.81 m/s2 downward (negative y direction). The wind resistance is proportional to velocity and is defined by constant k = 0.014 N / (m/s). The mass of the golf ball m = 46 grams.
1) Determine the horizontal x1(t) and vertical y1(t) positions as a function of time ignoring air / wind resistance in both the x and y directions.
2) Determine the horizontal x2(t) and vertical y2(t) positions as a function of time including air / wind resistance in both the x and y directions.
3) For the case ignoring wind / air resistance, calculate how long the ball is in the air (in seconds) and how far away the ball lands from where it was hit (in meters).
