the velocity time graph of a car start from rest and it accelerate uniformly at a rate 3m/s2 for 5seonds if attain the velocity which maintain for 1m the car then brought to rest by a uniform retardation after another 30m. draw the velocity time graph. find the acceleration. ...

a fruit drops from the top of a tree 40m tall, calculate. the time taken to reach the ground. the velocity just before it hits the ground.


Suppose that the demand functions for price increases and for price cuts facing an oligopolist are, respectively, Q1=560-80p1 and Q2=200-20p1 Suppose that the firm’s total cost function is TC=4Q+0.050Q^2 3.1 Derive the MR1, MR2 and MC functions facing the oligopolist. 3....

Important then very much go beat clara
