Question

Mark Stone glides off the ice onto the bench at a velocity of 2.41 m/s. He is slowed at a constant rate of 4.3 m/s2. How fast is Mark Stone moving when he slit 0.34 m down the bench?

Answer 1

Answer: 1.70 m/s

Step-by-step explanation:

suvat

s = 0.34m

u = 2.41 m/s

v = ?

a = -4.3 m/s2

t = ?

v^2 = u^2 + 2as

v^2 = 2.41^2 + 2*(-4.3)*0.34

v^2 = 2.8841

v = 1.698 m/s = 1.70 m/s
