To determine a car's maximum acceleration, you start from rest, press down hard on the accelerator pedal, and time how long it takes to get up to 26.8 m/s (about 60 miles per hour). It takes a powerful new electric car only 4.2 s to reach 26.8 m/s. What is the car's acceleration?
The car's acceleration is _ m/s^2.

Could someone . i have tried to solve myself but my calculation is off

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
