A 63 kg astronaut drifting with 7.0 m/s to the right with

respect to a spacecraft uses a jetpack to slow down.

Suppose it takes 14.0 s to come to a stop with respect to the spacecraft. What is the force exerted by the jetpack?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .
