Question

TO. A projectile is fired from point o at the edge of a chiff, with initial velochy s of 0r 60.0 mi's andv into the sea at point P. The time of fnlight of the projectile is4o 0 s, and it appreciable air resistance in flight. What is the horizontal distance D? Oy175 m/s, as shown in the figure. The projectile rises and then falls A) 675 m B) 956 m C) 2400 m D) 175 m E) 400 m An object has a position given by? (r)-I20m + (30?)+13.0m-(1.00) ty . where all quantities are in SI units. What is the magnitude of the acceleration of the object at time 1-2.00 seconds? 5s A. 100 m/s2 0.00 m/s2 D. 4.00 m/s2 E. 2.00 m/s B. C. 0.522 m/s2 The velocity and acceleration of an object at a certain instant are #2 (3.05x is (0.5 -(0.2 )) At this instant, the object is 12. s A) speeding up and following a curved path. B) speeding up and moving in a straight line. C) slowing down and following a curved path. D) slowing down and moving in a straight line. E) none of these. Two particles, A and B, are in uniform circular motion about a common center. The acceleration of particle A is equal to acceleration of particle B. The radius of particle A is 2.0 times the radius of particle B. The ratio of the speed of the motion of particle A to that of speed of particle B is closest to A) = 2 13. vB VB 1 VB E) none of the above

Explanation / Answer

ACCORDING TO THE CHEGG GUIDELINES I AM ALLOWED TO ANSWER ONLY 1 QUESTION AT A TIME.

1) HERE WE NEED TO FIND THE VALUE OF THE DISTANCE ( D) .

DISTANCE ( D) = S * t = 60.0 m/s * 40.00 m = 2400 m ========================ANSWER) OPTION C)
