How much tension must a rope withstand if it is used to accelerate a 1700-kg car
horizontally at 0.50 m/s^2 ? ignore friction.
what tension would be required to accelerate
it vertically at the same rate? ​

round the corners of the magnet that where it is stronger

hope this : )

the net force on the climber is 495 n acting downwards direction.

explanation:

the   forces acting on the climber are:

now, the net force on the climber = gravity - tension

= 950 n - 455 n

= 495 n

(this force acts downwards as the force of gravity acts downwards)
