During a training exercise a cannon ball is fired with a muzzle velocity of 70.5 m/s at an angle of 45° above the horizontal. Determine how far from the cannon the ball will land when it hits the ground.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario
