Hi! Doing some practice problems trying to get ready for a test and I cant seem to get the right answers! Please show me your steps and the final answer thanks so much!!
1. A stone is thrown outward from the top of a 36.7 m high cliff with a vertical velocity component of 25 m/s and a horizontal velocity component of 12.3 m/s. How many seconds will the stone be in the air?
2. A 1.5 N ball is thrown at an angle of 30o above the horizontal with an initial speed of 12 m/s. At its highest point, the net force on the ball is
Choose one answer.
A. zero
B. 9.8 N, 30 degrees below the horizontal
C. 14.7 N down
D. 1.5 N down
E. 9.8 N up
