Answer 1

A force shown in the F-x graph is applied to a 5 kg cart, which then coasts up a ramp as shown. The maximum height, y_max is 2.00 m, at which the cart can reach.

Explanation:

As per graph, the velocity at point,

x = 5 is v = `sqrt40` m/s.

Using conservation of energy,

`m/2sqrt((40)^2) = m xx 10 xx h`

h = 2 m
