Acar is rounding an unbanked circular turn with a speed of v = 35 m/s. the radius of the turn is r = 1500 m. what is the magnitude ac of the car’s centripetal acceleration?

The magnitude of the car's centripetal acceleration is ac= 0.816 m/s² .

Explanation:

r= 1500m

Vt= 35 m/s

ac= Vt²/r

ac= (35m/s)² / 1500m

ac=0.816 m/s²

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
