A ball is thrown horizontally with an initial velocity of 67 m/s at a height of 76 m. a) How long will it be in the air? b) How far horizontally will it travel? c) What is the final velocity of the ball when it hits the ground?

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

Particle A has m=10.0g, RA=(4.0, 0.0)m, VA-(-1.0, 2.0)m/s. Particle B has m=5.0g, R0.0, 6.0)m, VB (1.0,-1.0)m/s. A) What is the position of B relative to A? What is the velocity of B relative to A? B) What is the angle between the two relative vectors that you calculated in A)? C) What is the significance of this result? D) What is the momentum of each particle? E) What is the angular momentum of A about the origin? F) If these particles collided, what would be conserved, and under what circumstances?

Во Font Arial Bold B 2. In a basketball game, a player shoots the ball at a velocity of 4.31 m/s at 17.30 above the horizontal. A player on the other team jumps up and blocks the ball at the maximum height. A) Character How far horizontally does the ball travel to where it is blocked? B) How long is the ball in the air before being blocked C) If the ball wasn't blocked, what is the magnitude and direction of the velocity when the ball returns to the launch height?

In a ballistic pendulum lab we used the law of projectile to determine the initial velocity. The ball was released with some initial speed V from the table, the table has an altitude of 1.1 m and the ball land 2.3 m away. What is the muzzle velocity of the ball as it shot from the gun? 4.9 m/s O 7.0 m/s O 6.1 m/s O 8.0 m/s

student throws a heavy red ball horizontally from a balcony of a tall building with aninitial speed v0. At the same time, a second student throws a lighter blue ball horizontally fromthe same balcony with an initial speed v0 /2. Ignoring air resistance, which of the followingstatements must be true?a. The red ball hits the ground with the greater speed.b. Both balls hit the ground with the same vertical velocity component.c. Both balls hit the ground with the same angle of impactd. The balls reach the ground at the same instant.     More than one of the statements can be true.

a) the place where the rock lands.  b) the velocity of the rock (magnitude and direction) just before it lands.

Two projectiles are launched from the same point at the same angle, but the first one has twice the initial velocity compared to the second. The ranges R1 and R2 are: O A. R2 = 4R1 O B. R1 = 4R2 OC R2= 2R1 OD R1 = R2 O E None of the above.

Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. c) Find the average force exerted by the club on the ball. d) Find the average shear deformation of the club's 0.800 m long and 1.00 cm diameter steel shaft.

A hockey puck slides off the edge of a table with an initial velocity of 23.6 m/s and experiences no air resistance. The height of the tabletop above the ground is 2.00 m. What is the angle below the horizontal of the velocity of the puck just before it hits the ground? A) 72.6° B) 31.8° C 14.9° (D) 77.2° E 22.8°
