acceleration = (v-u)/t

t=4 second

v =-2 and u=10

a = (-2-10)/4

a=-3m/s^2

thanks

Hello here is your answer by Sujeet yaduvanshi ☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝

Question:-
an object with a mass of 10kg moves at a constant velocity of 10m/s. A constant force then acts for 4 sec on the object and gives it a speed of 2m/sec in opposite direction. The acceleration produced in it is,

Answer:-)initial velocity(u)= 10m/s
Final velocity(v)= -2m/s
Force=m(v-u)/t= 10(-2-10)/4= -30N
force=m*a
a=f/m= -30/10= -3m/$²
