1.2 Equations of Motion | SPH4U Kinematics Problems

Homework help for Nelson Physics 12 Chapter 1.2 Equations of Motion where we look at rectilinear problems also known as kinematics 1D examples.

You will be able to get the nelson physics 12 solutions to the following questions at a high school physics level with kinematics problems and solutions.

Motion in a Straight Line Example:
00:00 1. Upon leaving the starting gate, a racehorse accelerates at a constant 4.1 m/s^2 [forward] for 5.2 s. Determine the horse's
(a) displacement
(b) final velocity

07:44 2. An electron travelling at 7.72 x 10^6 m/s [E] enters a force field that reduces its velocity to 2.46 x 10^6 m/s [E]. The acceleration is constant. The displacement during the acceleration is 0.478 m [E].
(a) Determine the electron's acceleration.
(b) Determine the time interval over which the acceleration occurs.

Motion under gravity example:
15:32 6. You throw a ball straight up into the air at 18 m/s from a height of 32 m above the ground.
(a) Calculate the time the ball takes to hit the ground.
(b) Calculate the velocity of the ball when it hits the ground.
(c) Calculate the maximum height of the ball.
(d) Explain why you cannot use half the time for (a) to answer (c).
