Question

A woodchuck runs 24.8 m to the right in 4.73 s, then turns and runs 9.1 m to the left in 3.36 s.

Part (a) What is the magnitude of the average velocity of the woodchuck in m/s?
Numeric : A numeric value is expected and not an expression.
v = __________________________________________

Part (b) What is its average speed in m/s?
Numeric : A numeric value is expected and not an expression.
v = __________________________________________

Expert Solution

Step 1

Given

Displacements of the woodchuck is $s_{1} = + 24.8 m$ and $s_{2} = - 9.1 m$ (considering displacement to the right as positive and displacement to the left as negative)

Time for these displacements are $t_{1} = 4.73 s$ and $t_{2} = 3.36 s$
