The equation for the speed of the body has the form V = 2 + 6 * t find the movement of the body in 5 seconds.
June 30, 2021
Since the formula for the motion of any body has the form V = V0 + a * t, then from the equation of the body’s velocity it follows that the initial velocity of the body is V0 = 2 m / s, the acceleration of the body is a = 6 m / s².
S = V0 * t + a * t² / 2.
Distance covered in 5 seconds:
S = V0 * t + a * t² / 2 = 2 * 5 + 6 * 5² / 2 = 10 + 75 = 85 m.
Answer: The movement of the body in 5 s is 85 m.
