An artillery shell is fired with a minimal velocity of 440 m/s at 57o above the horizontal. To clear an avalanche, it explodes on a mountain side 48 s after firing. 1.What is the X-coordinate relative to it's firing point? 2.What is the Y-coordinate?

A car is traveling at 54.3 km/hr on flat highway. If the coefficient of friction between road and tires on a rainy day is 0.171, what is the minimum distance in which the car will stop? What is the stopping distance when the surface is dry and the coefficient of friction is 0.507?

An artillery shell is fired with an initial speed of 1.72E+3 m/s at an angle of 53.8o above the horizontal and returns to its original level before impact. 1.Neglecting air resistance, calculate the time it is in motion. 2.Calculate the horizontal distance traveled.

A ball is thrown vertically upwards with an initial velocity of 27.0 m/s. 1.Neglecting air resistance, how long is the ball in the air? (Remember that the ball goes up and then returns downward.) 2.What is the greatest height reached by the ball? 3.Calculate the first time where the ball has...
