A car traveling at 40 km h-1 speed upto 50 km h-1 in 4 seconds. Calculate the acceleration of the car

Question

Solve this numerical

Answer 1

To answer this question, first we need to define the equation for acceleration:

(v_f - v₀) /(t_f - t₀)

In this problem we are given the change in time (t_f - t₀)=4 seconds, v_f=50 km/hr, and v₀=40 km/hr.

4 s x 1 hr/ 3600 s = 1.11x10^-3

a (km*hr^-2)=(50-40)/1.11x10^-3

9009.01 km*hr^-2
