Aremote-controlled car is moving in a vacant parking lot. the velocity of the car as a function of time is given by Ο
β =[5.00m/sβ(0.0180m/s3)t2]i^ + [2.00m/s+(0.550m/s2)t]j^.
a. what is the magnitude of the acceleration of the car at t = 6.23 s ?
i already know that i need to use the derivative of the velocity equation given but i don't know what to do from there.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you donβt find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
