Question

You are walking in the forest with some friends when a wild bear shows up! Naturally, you all begin running faster. Assume that you had an initial velocity of 0.5 m/s. After running for 20 seconds, you are 50 meters away from where you started. If you accelerated at a constant rate, what must your final velocity be?

Answer 1

Answer:

Explanation: Here he is running with a uniform acceleration there for you can use motion equation for this

S = (V+U)×t / 2

S = Distance

V = Final velocity

U = Initial Velocity

t = time

50 = (V + 0.5 ) × 20 /2

V = 4.5 m/s
