Two cars, side by side, start from rest one with an acceleration of 4 m/s^2. Both travel in some direction. How far apart 9 seconds later? In meters. 7m/s^2 is for second car
R Two identical negative charges are placed 550. mm apart. The left object experiences a repulsive electrostatic force of 612N. A. What is the charge on each object? B. How many electrons must be removed from the left charge to make it neutral? C. In sequence the left object is touched to a third charge and then to the right charge. The left charge ends with a 2.00x104C. What was the value of the 3rd charge?
A package of mass 50 kg is dropped from a helicopter and experiences a drag force of 120 N due to air resistance. Find the resultant force and use it to calculate the acceleration of the package during the fall. Take the acceleration due to gravity as g = 9.81 m s-2 and give your answer in m s-2 to 1 decimal place. Answer: Answer m s-2
