the speed of a bobsled is increasing because it has an acceleration of 2.4 m/s2. at a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 450 n. the combined mass of the bobsled and its riders is 270 kg. (a) What is the magnitude of the force propelling the boblsed forward?
(b) What is the magnitude of the net force that acts on the bobsled?

Acceleration refers to the rate at which the velocity and direction of a moving object change over time. Anything is said to be sped when it goes straighter and faster or slower. Therefore, even though the speed is constant, travel on a circle increases due to the constant change in direction.

In what ways do velocity and velocity differ?

The rate at which a displacement varies is measured by its velocity. Speed changes occur at an accelerated rate. Its magnitude and orientation are both present, making it a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.
