A 20 kg box is moving toward you with a velocity of 5m/s. You push it with a force of 10 N for 20 seconds. a) Draw a force diagram for the box

b) Calculate the acceleration the box experiences

c) Calculate the velocity of the box after20s

d) Draw a position-time, velocity-time,

acceleration-time graph for the box

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
