Five persons A,B,C,D,E pull a 100 kg cart. With all five, acceleration is 3 m s⁻² east. If A stops, acceleration is 1 m s⁻² west. If only B stops, acceleration is 24 m s⁻² north. What is the cart acceleration when only A and B pull in their original directions?

Question

Five persons A,B,C,D,E pull a 100 kg cart. With all five, acceleration is 3 m s⁻² east. If A stops, acceleration is 1 m s⁻² west. If only B stops, acceleration is 24 m s⁻² north. What is the cart acceleration when only A and B pull in their original directions?

G1 Physics · Accepted Answer

Convert each acceleration into net-force vectors. From the change when A or B is removed, determine their individual force vectors and add them. The resultant corresponds to 25 m s⁻². Option C.
