I'M FAILING THIS CLASS PLEASE HELP BEFORE I CR A cart has a mass of 0.26 kg and is attatched by a string and a pulley, to a weight that has a mass of 0.50 kg. Draw and FBD (you don't have to)
a) calculate the acceleration of the cart if there is a kinetic frictional force of 0.10 N acting on the cart
b) calculate the magnitude of tension in the string

your answer is c! hope this : )

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.

the correct answer is d. stress, i just took the quiz
