Two tug boats are towing a large boat, of mass 22500 kg, back to shore. Tug boat 1 is pulling with a force of 5500 N at an angle of 35◦ north of the forward motion (similar to Worked
Example 2) and tug boat 2 is pulling with a force of 4907.8 N at an angle 40◦
forward motion. If the large boat is being pulled with constant velocity, and there is a resistive
force to the motion, then what size is the resistive force?

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
