In the first 10s of a horse race a horse starts from rest and ends with a velocity of 60km/hr. What is the horse's average acceleration during that time in m/s??
*** Round answer to the first decimal place ***

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

A40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the. volume of the ammonia if it’s pressure is changed to 8.4 kpa while its temperature remains constant.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
