Agolf club (mass 0.5kg) hits a golf ball (mass 0.03kg) with a constant force of 25n over a time of 0.02 seconds. what is the magnitude of the impulse delivered to the ball? select one: o a. 0.05 ns b. 1250 ns c.1.67 x102 ns d.12.5ns o e.8.00 x 104 ns

For a particular reaction, ? h = -144.6 kj and ? s = -301.2 j/k. calculate ? g for this reaction at 298 k.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant
