Initially, a car travels along a straight road with a speed of 35 m/s. if the brakes are applied and the speed of the car is reduced to 10 m/s in 15 s, determine the constant deceleration of the car.

Initial velocity"(u)"= "35 m\/s"
Final Velocity"(v)=""10 m\/s"
Time taken"(t)=""15 s"
Acceleration;
"a=""\\frac{v-u}{t}"
"a=\\frac{10-35}{15}=-1.67"
Therefore the constant deceleration of the car is "-1.67m\/s"
