A shopper in a supermarket pushes a loaded cart with a horizontal force of 13 N. The cart has a mass of 27 kg. (a) How far will it move in 4.0 s, starting from rest? (Ignore friction.) 3.84 (b) How far will it move in 4.0 s if the shopper places his 30 N child in the cart before he begins to push it? 3.02 Your response differs from the correct answer by more than 10%. Double check your calculations, m

A steam catapult applies a very large force to supplement the engine thrust of a jet fighter as it takes off from an aircraft carrier. The jet has a mass of 3850 kg ad must reach its take off speed of 75 m/s at the end of the 208 m fight deck. What is the combined force of the catapult and engines?

10. Refer to Figure. Block A has a mass of 3.00 kg, block B has a mass of 5.00 kg and block C has a mass of 2.00 kg. The pulleys are ideal and there is no friction between block B and the table. What is the acceleration of the masses? A 0.981 m/s B 1.86 m/s2 C 2.94 m/s2 D 4.20 m/s2

A 1.4 gram bullet is shot into a tree stump. It enters at a velocity of 341 m/sec and comes to rest after having penetrated the stump in a straight line. It takes 0.00032 sec to come to a stop after striking the stump. What was the force on the bullet during impact?  (answer in Newtons)

The maximum force that can be put on an egg without breaking it has been determined to be 15 N.  If the 0.15 kg egg is moving at 10.0 m/s and needs to be brought to a stop.  How much time will need to be allowed for it to slow down?

(2.2 m/s)î + (-7.8 m/s)j. Two of the forces are F = (1.5 N)i + (3.8 N)i + (-2.0 N) an Three forces act on a particle that moves with unchanging velocity v = F:= (-4,6 N)i + (3.8 N); + (-22 N)ê. What is the third force?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

Anjay’s mass is 70 kg. He is standing on a scale in an elevator that is moving at 5.0 m/s. As the elevator slows to a stop, the scale reads 750 N. Before it stopped, was the elevator moving up or down? How long did the elevator take to come to rest?

A 0.152 kg ball is attached to a string that is 62.2 cm long. The string will break if subjected to a tension force of 4.8 N. If a small child swings the ball in a horizontal circle around her head, at what velocity will the string break?

A rock, in deep space, has a rocket thruster, with negligible mass, attached to it. The rocket causes a force of 3,300[N]. If the rock has a mass of 4.62×104[kg], what is the acceleration experienced by the rock, due to this force alone? Express your answer in terms of m/s2.
