Question

You started to run at 10 km/h when you left your house and you arrived at school 30 minutes later. Assuming that your average acceleration was 30 km/h2, how fast were you running when you arrived?​

Answer 1

Answer:

Solution:

Using the equation of motion v = u + at

where v is the final speed

u=10 km/h is starting speed

a=30 km/h^2 is acceleration and

t=0.5 hours is time

v = 10 + (30 x 0.5)

=10+15

=25km/hr.
