Question

What is the displacement of a car whose initial velocity is 5 m/s and then accelerated 2 m/s2 for 10 seconds

Answer 1

The displacement of the car can be calculated using the formula:

d = v_i * t + 0.5 * a * t^2

Where d is the displacement, v_i is the initial velocity, t is the time, and a is the acceleration.

Substituting the given values, we get:

d = (5 m/s) * (10 s) + 0.5 * (2 m/s^2) * (10 s)^2

d = 50 m + 100 m

d = 150 m

Therefore, the displacement of the car is 150 meters.
