A 10 kg block of ice is at rest on a frictionless horizontal surface. A 1597 N force is applied to the block for 10 ms. During this time interval, the change of the velocity of the block is: 01.06 m/s 3.19 m/s O 2.28 m/s O 1.60 m/s O 0.80 m/s Clear my choice

A 4.2-g bullet leaves the muzzle of a rifle with a speed of 326 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.78-m-long barrel of the rifle? ____ N

A tennis ball is flying eastward towards a wall with a speed of 33.7 m/s. After bouncing against the wall, it's flying westward with a speed of 21.9 m/s.  If the mass of the ball is 0.1 kg, and the time the tennis ball is in contact with the wall is 0.032 s, what is the magnitude of the force in N the ball exerts on the wall?

An antitank weapon fires a 3.00-kg projectile which acquires a speed of 50.0 m/s after traveling 90.0 cm down a launching tube. Assuming the projectile was accelerated uniformly, what was the average force that acted on it? a. 4.17×(10^3)N b. 3.62×(10^3)N C. 2.82×(10^3)N d. 2.00×(10^3)N

A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2?  Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?

A 0.25 kg arrow with a velocity of 12 m/s to the east strikes a target and pierces the bull's-eye of a 6-kg target. Based on the scenario, which of the following variables represent 12 m/s? M2 OV₂ O V1 Om₁ Black

7. During a snowball fight, a 0.30-kilogram snowball traveling at a speed of 17.0 m/s hits a student in the back of the head. If the contact time is 0.10 s, what is the magnitude of the average force on the student's head? N ssf f60° Ossi 09 JS 50 ssf60

A 47 kg skater is standing still in front of a wall. By pushing against the wall she propels herself backwards with a velocity of -1.1 m/s. Her hands are in contact with the wall for 1 seconds. Ignoring friction and wind resistance, find the average force she exerts on the wall? Faverage

A 1.0 kg object has a velocity of 5.0f m/s at t = 0. A constant resultant force of (3.0î + 4.0f ) N then acts on the object for 3.0 s. What is the magnitude of object's velocity at the end of the 3.0 s interval? A B D E 9.8m/s 17.7m/s 9.2 m/s 15.0 m/s 16.3 m/s Lütfen birini seçin: O A O B O C O D O E
