10-13. The velocity of a particle at = 2 s is 50 m/s 140° average acceleration during the time interval. at = 6 s, it is 50 m/s/15° Calculate the

A movie stunt driver on a motorcycle can fly over a wide ditch with certain angle and initial speed. However, if he speeds horizontally, will he crosses this ditch? Consider his motion as projectile, and the two sides of ditch have equal altitude. Yes, he will if his initial velocity is big enough No, theoretically he will never cross this ditch It depends on the weather condition It depends on how powerful of his motorcycle Is it 1,2,3, or 4

A ball is thrown Horizontally with a velocity of 05 m/sFrom the top of a tall cliff . What is the speed of the ball 2 seconds later ? What vertical distance had the ball fallen 2.0 seconds later ?

A ball is kicked with an initial speed of 40 m/s at an angle of 30 degrees from the top of a 500m cliff. How fast is the ball moving just before it hits the ground? Answer using kinematics.

A man throws a stone upward at an angle of 30° to the horizontal. It lands 60 m measured horizontally and 2 m below his arm measured vertically. Determine the time of flight and the initial velocity of the stone.

A ball is launched from a 10.0 m building with an initial speed of 15.0 ?/?. If the ball’s speed when it reaches its maximum height is 1/3 its speed when it is at half its maximum height, determine ball’s launch angle and the ball’s angle at impact.  This is all the information i was given!

A ball was thrown from the ground at an angle of 28 degrees with the horizontal with an initial speed of 19 m/s. Calculate the highest distance it can reach.

The coordinates of a particle moving in a plane are given by r = 4 cos 6t and y = 6 sin 6t find the angle between position vector 7 and velocity vector i at time t: = T/12

One of the fastest recorded pitches in major-league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h. If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? ft

What is the final 23 velocity after 5 sec? 6 m/s (b) 15 m/s (c) 30 m/s (d) 35 m/s Question. The horizontal component of the acceleration (a.) for an ideal projectile motion is 24 equal to zero. (а) | True (b) False Question A projectile is launched with an initial velocity of 30 m/s at angle of 30° above the 25 horizontal. What is the magnitude of its velocity at t-2 secf. (a) 15.75 m/s (b) 10.2 m/s (c) 26.38 m/s (d) 2.2 m/s
