A 3-kg ball has a momentum of 43 kg m/s. What is the ball's speed?! Please report answer to two significant figures and use the abbreviated form of the unit. Answer:
atom is 6.64 x 10-27 kg. (a) the escape speed from Earth, 1.12 x 104 m/s (b) the escape speed from Mercury, 4.27 x 103m/s Your response differs from the correct answer by more than 10%. Double check your calculations. K
A 1.5 g particle has momentum 4.0×105 kg⋅m/s What is the particle's speed? Express your answer using two significant figures.
2. A bicycle has a momentum of 24 kg•m/s. What momentum would the bicycle have if it had. e. three times the mass and was moving with one-half the speed? f. three times the mass and was moving with twice the speed?
Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...
e SI entum is kg x m/s. The momentum of an object is always positive. 10 pts Question 11 A2.9-kg cart moving to the right with a speed of 5.2 m/s has a head-on collision with a 5.2-kg cart that is initially moving to the left with a speed of 9.6 m/s. After the collision, the 2.9-kg cart is moving to the left with a speed of 3.7 m/s. What is the final velocity of the 5.2-kg cart? Equation: miui...
PROBLEM (a) Find the speed of the proton at x 0.0500 m if s released from rest at x -2.00 cm in a constant electric field with magnitude 1.50 x 103 N/C, pointing in the positive direction. (b) Find the initial speed of an electron fired from x 2.00 cm given that its speed has fallen by half when it reaches x 0.120 m STRATEGY Apply conservation of energy, solving for the unknown speeds. Part (b) involves two equations: the...
