A car travels from point A to Be in 3 hours and returns back to point A in 5 hours .Points A and B are 150 miles apart along straight highway .Find the average velocity for A to B ,B to A and for the entire trip in miles per hour

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

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.

Suppose you hit your hand against the edge of table. using newton’s third law of motion why does my hand hurt? explain
