Rocket Cart on a Track

Rocket Cart on a Track#

A \({{params.m}} \ \rm{kg}\) cart uses rocket propulsion to accelerate on a track. The rockets are known to deliver \({{params.F}} \ \rm{kN}\) of thrust total. The kinetic friction coefficient is \({{params.nu}}\). The cart begins at rest, and the rockets are on for \({{params.t}} \ \rm{s}\).

Rockets mounted on a cart are pushing it forward on a track.

Part 1#

What is the maximum speed of the cart?

Answer Section#

Please enter in a numeric value in m/s.

Part 2#

How much work was done by the rockets?

Answer Section#

Please enter in a numeric value in kJ.

Part 3#

If the rockets are angled upward to cancel friction, what is the new maximum speed of the cart?

Answer Section#

Please enter in a numeric value in m/s.

Part 4#

How much work was done by the rockets this time?

Answer Section#

Please enter in a numeric value in kJ.
