A hockey stick is in contact with a 165-g puck for 22.4 ms; during this time, the force on the puck is given approximately by F(t) = a + bt + ct2 where a = −25.0N, b = 1.25 × l05N/s, and c = −5.58 × 106 N/s2. Determine (a) the speed of the puck after it leaves the stick and (b) how far the puck travels while it’s in contact with the stick.

- A block with mass m₁ = 0.600 kg is released from rest on a frictionless track at a distance h₁ = 2.55 m above the top of a table. It then collides elastically with an object having mass m₂ = 1.20 kg that is initially at rest on the table, as shown in the figure below. h₁ իջ m m2 (a) Determine the velocities of the two objects just after the collision. (Assume the positive direction is to the right. Indicate the direction with the signs of your answers.) V1= m/s m/s (b) How high up the track does the 0.600-kg object travel back after the collision? m (c) How far away from the bottom of the table does the 1.20-kg object land, given that the height of the table is h₂ = 1.75 m? m (d) How far away from the bottom of the table does the 0.600-kg object eventually land? marrow_forwardAn estimated force-time curve for a baseball struck by a bat is shown in the figure below. Let F F(N) Fmax TÀ 0 t (ms) 0 la (a) the magnitude of the impulse delivered to the ball N.S (b) the average force exerted on the ball KN = 17,000 N, t = max a 1.5 ms, and t₁ = 2 ms. From this curve, determine the following.arrow_forwardThere are many well-documented cases of people surviving falls from heights greater than 20.0 m. In one such case, a 55.0 kg woman survived a fall from a 10th floor balcony, 29.0 m above the ground, onto the garden below, where the soil had been turned in preparation for planting. Because of the "give" in the soil, which the woman compressed a distance of 15.0 cm upon impact, she survived the fall and was only briefly hospitalized. (a) Ignoring air resistance, what was her impact speed with the ground (in m/s)? m/s (b) What was the magnitude of her deceleration during the impact in terms of g? g (c) Assuming a constant acceleration, what was the time interval (in s) during which the soil brought her to a stop? S (d) What was the magnitude of the impulse (in N⚫ s) felt by the woman during impact? N⚫s (e) What was the magnitude of the average force (in N) felt by the woman during impact? Narrow_forward
- Example Two charges, one with +10 μC of charge, and another with - 7.0 μC of charge are placed in line with each other and held at a fixed distance of 0.45 m. Where can you put a 3rd charge of +5 μC, so that the net force on the 3rd charge is zero?arrow_forward* Coulomb's Law Example Three charges are positioned as seen below. Charge 1 is +2.0 μC and charge 2 is +8.0μC, and charge 3 is - 6.0MC.
