Assume a golf ball leaves a tee moving at 40 m/s at an angle of 40o on ground. The vertical acceleration of the ball while on its way up is -9.8 m/s2. Using the ball, the ball hit the ground at 5.5 sec. Find at what two times is the golf ball at height of 24 meter?
A particle of mass 3 kilogram is attached to the end of a string of length 4 meter, whose other end is fixed. Determine the least horizontal speed with which it must be protected from the lowest point, if it is to describe complete vertical circles
